Changes in LTspice XVII

The changes from the old version LTspiceIV to the new version LTspiceXVII are as follows.

Changes from LTspice IV to LTspice XVII
  • 64-bit compatible (simulation speedup)
  • Character font supports Unicode (Japanese can be described in the schematic)
  • GUI change (improves operability and usability)
  • etc.

As a major change, LTspiceXVII supports 64 bits, and according to the “LTspiceXVII Startup Guide”, simulation is 26% faster than previous versions of LTspiceIV.

In addition, because the character font corresponds to Unicode, it is possible to describe Japanese in the circuit diagram.

And the change in GUI has improved operability and usability compared to previous versions of LTspice IV.
