AMS netlist problem
Feb 14^th, 2007, 2:17pm

When I use AMS Netlister netlist some circuit block, it generates several error:

Error: Value "1" of property "m" (CDF name "m") on instance "T0" is a string.
Ensure that value of "m" factor property is of type integer or real.
......
where T0.. are transistor in a kit.

So I use CIW->Tool->CDF->Edit... to change CDF, but since the transistor is from a design kit, I can only open it in "read-only" mode. Is there anyway to overcome this problem? Thanks.

AMS netlist(cell-based) require correct parameter type setup. You need to change m to "real" or "integ" type in CDF. This is right thing to do since it should be "real" or "integ" parameter type based on the CDF parameter definition. You can either ask PDK admin to change that or copy the PDK lib in your local to change that.

The other thing you can try is to use OSS netlisting in AMS-ADE which can avoid to have CDF change but you may run into other issues...
