Title: TT Post by TT on Apr 20th, 2006, 6:58am Hi, I am trying to use pPar in a behavioral model. It works fine until I try to netlist. The netlister does no pass the value of my CDF parameter but instead still writes pPar("myvalue"). I have checked the CDF options and set the parAsNumber to yes ... but still nothing happens ? Did somebody meet this problem before ? TT |
Title: Re: TT Post by Andrew Beckett on Apr 20th, 2006, 2:17pm Before you start DFII, enter: Code:
if you're using csh/tcsh, or, Code:
if you're using ksh/bash, or, Code:
if you're using sh as your shell. This will then tell the spectre netlister to work in "Analog" mode, rather than "Digital" mode - there are two different parameter passing mechanisms (for historical reasons). You can also type: Code:
in the Command Interpreter Window (i.e. use the above SKILL functions) to achieve the same effect. Regards, Andrew. |
Title: Re: TT Post by basf on Mar 28th, 2007, 3:38am Who knows how to make Cadence add scaling information in the netlist? Is there any variable to do that. I just want to automatically add ".option scale=1e-06" string in generated netlist. |
Title: Re: TT Post by Andrew Beckett on Apr 12th, 2007, 1:46am For spectre this is under the Simulation->Options->Analog. For the hspiceD interface, it's under Simulation->Analog Options->Model Analysis Options->General Options . The corresponding cdsenv settings (to initialise these fields) can be done with the SKILL functions: Code:
Regards, Andrew. |
Title: Re: TT Post by rajdeep on Dec 25th, 2007, 4:26am Well, does it work for verilog behavioral models also?? I mean, is the meaning of pPar at all understood by the verilog netlister? I'm using spectreVerilog and set the variable CDS_Netlisting_Mode to "Compatibility". Rajdeep |
