What's Good About Allegro AMS Simulator PSpice Model Encryption? It’s in the 16.6 Release!

Comments(0)Filed under: AMS simulation, model editor, AMS simulator, AMS, pspice, Allegro 16.6, Allegro AMSWith the 16.6 Allegro AMS Simulator (PSpice) release, you now have a new AES 256-bit encryption algorithm. This makes the encryption utility of PSpice and the Model Editor both faster and more robust. You will still be able to decrypt models encrypted using the DES algorithm available in earlier releases. Both used-defined and multi-command line modes are supported.


Read on for more details …


User-Defined Encryption


Set the environment variable CDS_PSPICE_ENCKEYS with a value that points to a .csv file which contains the <filename>, <keys>, pairs.


Command-Line Usage


The PSpiceEnc command now has a new option to specify modes. The syntax being mode <n> or Mode <n>, where n can be 0, 2, or 3 as described below:

PSpiceEnc [-e/E | -i/I | -n/N | -p/P] [-mode <>] inputFilePath outputFilePath

0: Uses the prior 16.5 Encryption scheme.
2: Uses DES Encryption with advanced data security (available in 16.5).
3: Uses AES Encryption. This is the default for 16.6 and later releases.


Please share your experiences using these capabilities.
