What is Electrical CAD?

CAD

Types of CAD

Types of CAD
  • Electrical CAD
    • Circuit Design CAD
    • PCB Design CAD
    • Electrical Control Design CAD
  • Mechanical CAD
  • Architectural CAD
  • Civil Engineering CAD

etc.

CAD (computer-aided design) generally refers to software for design and drafting using a PC.

The use of CAD has improved the efficiency and accuracy of design and drafting work compared to handwriting.

There are various types of CAD, and the ones introduced in this article are “circuit design CAD” and “PCB design CAD.

As simulation and analysis functions are added to “circuit design CAD” and “PCB design CAD”, they are sometimes referred to as EDA tools (electronic design automation tools).

Price Structure

The following are the main circuit design CAD/PCB design CAD price structures.

Price Structure
  • Perpetual License + Maintenance Cost
  • Fixed Term License
  • Subscription License
  • Free Trial License
  • Freeware/Open Source Software

Perpetual License + Maintenance Cost

A perpetual license is a price structure adopted by most CAD vendor.

However, in the case of CAD, there will be periodic costs for maintenance, support, and version upgrade.

This confusing pricing makes it difficult for the user to understand the overall cost.

Fixed Term License

With a fixed term license, you pay a usage cost every certain period of time.

The price structure is easy to understand, but there may be restrictions such as term limits or optional cost for additional features.

Subscription License

A subscription license is the same as a fixed term license in that you pay a recurring cost, but it focuses more on user requests to improve the performance and functionality of CAD.

For example, with video streaming services such as Netflix, there are always new videos available to watch, so the quality of the product offered will increase despite the same monthly cost.

CAD for subscription license is also thoroughly user-first, with the ability to always use the latest version and easy contract and cancellation.

Free Trial License

A free trial license allows you to experience the software for free, with some restrictions on the paid license.

Restrictions include board size, number of layers, number of component pads, etc., and it cannot be used for commercial purposes.

Freeware/Open Source Software

Freeware/open source software CAD is essentially free to use.

Freeware basically does not disclose its source code. It is often provided as a personal hobby, or by PCB business companies or electronic component online shopping companies for sales promotion.

Open source software is based on the premise that “the source code is publicly available” and “redistribution is possible. Not only the originating developer, but also many people around the world can participate in the development.

License Authentication

There are four main types of license authentication methods for circuit design CAD/PCB design CAD.

Private ServerEXCELLENTPOORUNNECESSARYNECESSARY

USB Dongle

USB dongle authentication is a USB terminal-type hardware with an activation key inside, which is connected to the PC to activate the CAD.

The license key can be managed physically, but it needs to be sent, so it takes several weeks before the license is available, and it is difficult to take it outside the company for security reasons.

Standalone

Standalone authentication means that you can obtain a license from the official web site of the CAD vendor in advance and activate the license in an offline environment.

However, since a license is required for each PC used by the user, it is difficult to share the CAD.

Network

Network authentication is to access the license server of the CAD manufacturer for activation.

It can be used anywhere as long as there is an Internet connection, and the license can be shared very easily.

Private Server

Private server authentication involves setting up a license server in the company and then activating the license over a LAN.

This is sometimes called network authentication, but in this case, the license server is installed inside the company, making it almost impossible to use outside the company.

Features of Circuit Design CAD

Circuit design CAD is a software for creating circuit schematics. The created schematic data can be passed on to the PCB design CAD.

The main features of circuit design CAD are as follows.

Features of Circuit Design CAD
  • Improving the Efficiency of Design and Drafting Work
  • ERC/DRC
  • Linking with Circuit Simulator
  • BOM (Bill of Materials) and Netlist Output

etc.

Improving the Efficiency of Design and Drafting Work

Circuit Design CAD Design and Drafting Work

By using circuit design CAD, you can improve the efficiency of your design and drafting work.

For example, schematic symbols can be called up from the parts library, and wiring between each component can be processed quickly and accurately compared to handwriting.

However, with the standard parts library provided by free circuit design CAD, there are few components that can be used, so in many cases you will have to create your own.

It takes a lot of time to create schematic symbols and footprints, and there is a possibility of making mistakes.

For commercial purposes, it is better to use a paid circuit design CAD, because if even one of the footprints is different from the actual component and you proceed to PCB manufacturing, you will have to rebuild everything.

Also, it can be freely edited and copied so that it can be used in the next time.

ERC (Electrical Rule Check)

Circuit Design CAD ERC
Circuit Design CAD DRC

After creating a schematic, you can perform an ERC (Electrical Rule Check) to confirm that there are no electrical errors in the wiring.

If there is a wiring error, the CAD will display the result as an error or warning, allowing you to correct the mistake early in the design process.

There are also circuit design CAD with DRC (Design Rule Check) functionality. It can check the layout to make the schematic easier to read.

The items to be checked for ERC/DRC can be selected at the user’s discretion in the circuit design CAD settings.

Linking with Circuit Simulator

Circuit Design CAD Circuit Simulator

Recently, there has been an increase in the number of circuit design CADs that can be liked with circuit simulators such as LTspice, PSpice, and HSPICE.

The circuit simulation can be performed directly from the schematic created by the circuit design CAD. Therefore, there is no need to create a schematic on the circuit simulator side.

BOM (Bill of Materials) and Netlist Output

Circuit Design CAD BOM

Circuit design CAD can output BOM (Bill of Material) and netlist.

BOM output can be customized, so it is easy to create company-specified BOMs.

Netlist is “the connection data between components in a schematic”.

Usually, netlist output is available in a variety of third-party formats other than CAD vendors.

This allows you to deal with different CAD vendors when you outsource PCB design to your subcontractors.

In other cases, it can output a netlist for SPICE, which can be verified with circuit simulators such as LTspice, PSpice, and HSPICE.

Features of PCB Design CAD

PCB design CAD is software for pattern work by placing components on a PCB on data.

The created PCB layout data is used for PCB manufacturing and mounting. Usually, this is done by a PCB manufacturer.

The main features of PCB design CAD are as follows.

Features of PCB Design CAD
  • Improving the Efficiency of PCB Layout
  • Linking with Auto Routing Tool
  • DRC/MRC
  • 3D Functions
  • Gerber Data Output
  • Linking with Analysis Software

etc.

Improving the Efficiency of PCB Layout

PCB Design CAD PCB Layout

PCB design CAD can be used to improve the efficiency of PCB layout.

Rather, PCB design CAD is essential in PCB design because it is almost impossible to deal with multilayer boards by hand.

If the vendor is the same, you can have the circuit design CAD output data to the PCB design CAD for layout of the PCB.

Since the connection status is known, there is no wiring error in pattern work. It is also easy to modify and change the pattern work.

You can also handle schematics from other vendors as long as the netlist data is available.

Linking with Auto Routing Tool

PCB Design CAD Auto Routing Tool

For circuits that require many wiring points, such as CPUs and FPGAs, you can save time by linking an auto routing tool.

However, it does not take electrical characteristics into account, so power supply lines, analog lines, etc. must be wired manually in advance.

DRC/MRC

PCB Design CAD DRC
PCB Design CAD MRC

DRC (Design Rule Check) can be performed to check for violations of design rules for wiring, vias, etc.

Generally, DRC is performed after board layout is completed, but some PCB design CAD perform DRC in real time, allowing for error-free wiring work.

There are also PCB design CAD with MRC (Manufacturing Rule Check) functionality, which can be used to check for violations of manufacturing rules such as clearance between components and silk lettering angles.

The items to be checked for DRC/MRC can be selected at the user’s discretion in the circuit design CAD settings.

3D Functions

PCB Design CAD 3D Layout

You can use the 3D viewer to view the designed PCB and check if the components are placed on the PCB as you imagined.

It can also be linked to a mechanical CAD to check the interference of PCBs and components in the case and to take thermal analysis.

Gerber Data Output

PCB Design CAD Gerber Data

PCB design CAD can output gerber data (manufacturing files and drill files) for PCB manufacturing.

The “Gerber format” is almost a standard format in the PCB industry.

Linking with Analysis Software

PCB design CAD can be linked to analysis software such as SI/PI analysis and EMC to perform various simulations before PCB manufacturing.

Nowadays, electronic products are required to have lower voltage, higher signal speed, smaller size, and more functions, so these analyses are becoming more and more important.

How to Select Circuit Design CAD/PCB Design CAD

The following is a summary of important points to consider when selecting a Circuit Design CAD/PCB Design CAD.

Note that open-source CAD is inferior in terms of support, so it is basically recommended to choose from paid CAD.

Also, please refer to “Comparison of Circuit Design CAD/PCB Design CAD” for a detailed comparison of the differences between each CAD.

How to Select Circuit Design CAD/PCB Design CAD
  • Cost Performance
  • Usability/Product Performance
  • Support

Cost Performance

When introducing a Circuit Design CAD/PCB Design CAD, aren’t you concerned about the “price”?

However, it is very important to consider “cost performance” rather than simply choosing free CAD.

For example, if the labor cost is \$50/hour and the price of CAD is \$1,000/month, it is worth implementing if it can save more than 20 hours/month of work compared to free CAD.

Example of Cost Performance Approach
  • Price of CAD: \$1,000/month
  • Labor Costs: \$50/h
  • Break-Even Point:\$1,000÷\$50=20 hours/month

Therefore, it is necessary to select a CAD system that strikes a balance between “Usability/Product Performance” and “price”.

Note that even paid CAD offer a free trial edition, which can be used for hobby use. Some support, such as online manuals and forums, may be available.

Usability/Product Performance

Naturally, the Circuit Design CAD/PCB Design CAD to be introduced must have the performance required for design work?

Paid CAD meets the basic specifications and offers various functions such as parts library, auto routing, 3D functions, and linking with circuit simulators and various analysis software.

“Creating component data for schematic symbols and footprints” is a particularly time-consuming task, so having a component library available can significantly reduce design time.

However, the higher the performance, the higher the CAD price tends to be, so be careful not to purchase CAD that is over-specified beyond their design level in terms of cost-effectiveness.

In addition, since these Circuit Design CAD/PCB Design CAD are designed for professionals, they tend to be packed with too many functions, making settings and operations more complicated. A good UI/UX is also important.

Recently, by linking an online electronic component company with a parts information database, some CADs can check the inventory and prices of parts used in circuits.

Basically, all paid CAD offer a free trial edition, so it is a good idea to actually use and compare them when selecting a CAD.

Free CAD usually does not have the ability to work with online electronic component companies. This is the difference between free CAD and paid CAD.

Support

Paid Circuit Design CAD/PCB Design CAD are well supported.

Recently, in addition to telephone and e-mail, some companies have also established Internet-based support systems, such as webinars, online manuals, and forums, which are becoming more convenient.

Even if some problems occur in the operation of the CAD, the company that sells the paid CAD is basically quicker to respond.

Free CAD, on the other hand, is basically unsupported because it is funded by the authors’ volunteer spirit and donations.

If a freeze or file crash occurs, it is the user’s own responsibility, and we do not know when stable version will be released.

Also, some people say that well-known free CAD is explained a lot in books and websites, but in reality, many people do not know how to use it only from those explanations.

It is a fatal disadvantage in the job to have design work stalled for days, so it is better to choose from a paid CAD system with a good support system.

KiCad is well known as an open source CAD. However, we regularly receive questions on how to use KiCad on this site, perhaps because of the lack of support available, and we feel that it is better to use “paid CAD”.

Comparison of Circuit Design CAD/PCB Design CAD

Here is a list of recommended circuit design CAD and PCB design CAD.

In some cases, a free trial edition is available, so you should definitely try it out for yourself.
