Netlist creation error

yongs

Hi, I'm trying to use the schematics and simulation setups provided in CMOSedu.com.

When I added IC6.1 library (I'm using virtuoso 6.1.5 version) and other directories and ran the spectre simulation, I got Netlist Error:  

Could not find netlist procedure:ABbnNetlistProc instance "M0" in cell-view "Ch26_IC61" "Fig26_10" "schematic"

for all of the 3-terminal nmos and pmos transistors.

In the CDF editing window, the netlistProcedure field is written as "ABbnNetlistProc". After I deleted 'ABbnNetlistProc' and empty the field, the error message disappeared and netlist could be created, however, there's another error message: Error found by spectre during hierarchy flattening. ERROR (CMI-2116): M0: Too few terminals given (3 < 4) while running simulation. 

Any suggestion to solve this error?

  •  Hi,

    I don't have time to download and install materials from the site that you mentioned, but the general message seems to be that the netlist procedure ABbnNetlistProc is not defined - this is required to netlist the MOS component's bulk terminal.  Check that your start up procedures are loading SKILL from a .cdsinit file, or perhaps from a library libInit.il file (in the PDK library, for example) - this is most likely where the procedure should be loaded from. If this information does not help, you could look through *.il files and search for the ABbnNetlistProc, it is most likely defined in one of them somewhere but not being loaded, hence the error.

    Good luck.
