A QSPICE bug while working with s-parameters converted to .lib

Hi,
I encounter a problem while working with s-parameters with QSPICE.
I used the s2spice-2.1.0-win32.exe tool to convert a .s3p file to a .lib file. This method works flawlessly and very fast in LTspice. In QSPICE, however, I ran into several problems:

  1. Copying the .lib file into the schematic takes an unusually long time.
  2. The solver cannot handle the units in the .lib file, e.g.:
    +( 8.000000e+07Hz, 4.031277e-03, 1.795054e+02)
    It appears that the “Hz” unit is not being handled properly.
  3. Even after manually removing the “Hz” from the .lib file, the solver still fails with the numerous warnings, such as:
    Warning: Unexpected number, “4.009817E-001”, in device E11•X1.

Since LTspice handles this flow without issues, I believe this may be a bug in QSPICE.

Thanks,
I sent an email to Mike. Let’s see if he will fix it.

That’s right, not to fix it, but to add an option such as in LTspice.
