Question: I recently downloaded a model from a major manufacturer and I'm having trouble getting
it to work. I installed it in the way your manual describes and all went well. But then I tried running
a circuit with the part in it and I get the following message.
Unknown command.
$CDENSTART
Answer: The problem is that the file is encrypted. $CDENSTART defines the point at which
encryption starts. Only the headers are left in readable text. The crucial part of the file, the SPICE
netlist describing the model, is encrypted so that only PSPICE can read it. The purpose of the encryption
is said to be protection of the proprietary content of the model, but it also prevents Micro-Cap
or any other simulator but PSPICE from reading it. We recommend that you ask the manufacturer
for an unencrypted model. Often they will do this if you sign a non-disclosure agreement.
Question: I am trying to use Micro-Cap 11 in a computer with Windows 8 but the 64 bit version
is not able to run. I have tried with Windows 7 compatibility settings but it still does not work.
Answer: The problem is in the MC11 code that detects the number of processors in your system.
If you have 16 or more processors, then MC11 versions up to and including MC11.0.0.8 will not
properly run the 64 bit version, although the 32 bit version runs fine.
MC11.0.0.9 corrects the problem. You can download the updated 64 bit version (mc11_64.exe) and
also the updated 32 bit version (mc11.exe) directly from the Help menu or you can download it from
the web site Users Section.
