Title: Using Spice-In on CDL netlist with 3.3V and 1.8V Mosfets. Post by huffdave on Apr 6th, 2014, 7:23pm So I have a CDL netlist that has both 1.8V and 3.3V mosfets and I want the model name "pmos_1p8" and "pmos_3p3" to appear on the p-devices respectively after import. (Same syntax for the nmos devices). In the CDL netlist, I changed all of the 1.8V device model names from "pmos_1p8" to just "p" and the "pmos_3p3" device model name to just "pm". (It's a requirement of CDL-In that this parameter be 2 characters max). Then I set up a device mapping file as follows: devMap := nfet n propMatch := subtype n termMap := DD GG SS BB propMap := WW LL addProp := modelName nmos_1p8 devMap := nfet nm propMatch := subtype nm termMap := DD GG SS BB propMap := WW LL addProp := modelName nmos_3p3 (Same syntax for the pmos devices). After running SpiceIn it created a "subtype" property under "User Properties" as "nm" or "n" depending on which device it mapped. However, the model field stays blank even if I change the "addProp := model" instead of "modelName" - it doesn't matter what I do. How do I get the right model name in the "model" field after reading in the netlist?? Thx, -Dave |
