cds_generic nmos extracting as 4-terminal

jmoriarty

Using IC6.1.5-64b.500.9.  

Instantiating "nmos" (not "nmos4") symbol view from "cds_generic" library in which the model field is populated with "mod".  It extracts as  follows:

M6 (0 0 0 0) mod

The symbol view has only 3 terminals, and there are only 3 terminals in the pin list. There appears to be an error in the "spectre" view, which shows 4 terminals.  Only fix is to copy "symbol" and "spectre" views to an editable library and delete a terminal from the "spectre" view.  If this is indeed an error, can it be corrected in the next release?  If there is already an open ticket I appologize for not finding it.

 Thanks.

    Hi jmoriarty

    Actually "cds_generic" is not one of the libraries that can be found in Virtuoso installation. I believe that it has been most likely created by your CAD support. You will need to get their help to resolve the issue. In the meantime, you can try using "nmos" cell from "analogLib" library. Just add the following line in your cds.lib file:

    DEFINE analogLib $CDSHOME/tools/dfII/etc/cdslib/artist/analogLib
