Problem with Simulating Design using Spectre

govilv

 I have created a schematic using Virtuoso 6. When I open the ADE, it says "(deLicense-7) Could not get a license for ADE L. Would you like to try to get a higher-tiered license to run this product?"

When I click on Yes, it starts the ADE, but when I set up the analysis and click on "Netlist and Run", it comes out with an error -

"Error Unable to locate 'spectre' executable in the specified path. To set the correct path, use setShellEnvVar() in CIW."

I am new to this kind of problem and when I try to check my spectre version and type "spectre -W" in the CIW, it gives me errors. Am I missing a piece of software or it can be fixed without installing anything else?

Please help. Thank you.

 Raj.

     Hi,

    You can download/install the MMSIM releases from the downloads site, using InstallScape (you might need to download and install this first, the details are also on the downloads site - it is available alone or as part of the Lic+Config Utils package).

    Yes it is possible to use a newer (e.g. MMSIM7.1) version of spectre with the IC61x release (or IC5141 for that matter).

    Once installed, you will want to have spectre in your path in addition to the IC release tools; if you are using the IC61x tools then I don't think it will matter if MMSIM is in the path first or after the IC tools, but as you noted, if using IC5141, spectre is included in that release, so if you wanted to use a newer version of spectre, MMSIM would need to be in your search path earlier than the IC tools.

    The path to add is <mmsim_installation_dir>/tools/bin, this should be sufficient to pick up spectre.

    Hopefully this answers all your questions.

    Regards,

    Lawrence.
