set design variables in ADE XL

nzborsti

 Hi,

I am new to Cadence and I am using ADE XL (Version IC6.1.4.500.6)  for the first time.  

I wrote a simple model for a low-pass-filter by means of verilog ams. This model  includes some paremeters such as "nst_0","pst_r" etc.

 

These paramters show up, when I open the" Edit Object Properties" of the low pass filter, in the schematic of my testbench. 

Now I want to start a simulation of this testbench by means of ADE XL. To do this I also wanted to add the parameters "nst_0" to the "design Variables".  How is that done?

 

I already tried to assign a string " nst" to the value of "nst_0" in the "edit Object Properties" Window. After that I added a Design Variable in the Virtuoso ADE XL window named "nst" and assigned a value to this variable. But this didn't do the job cause everytime I hit the simulate button a error comes up:

ncelab: *E,CUBSPA (./netlist.vams,22|22): Assignment of string to real or integer type parameter.

 

I am looking forward to your help.

  •  Hi,

     

    okay problem is solved. For the sake of completness I would like to tell you , how I have managed to get around this problem:

     

    1) open the CDF Tool 

    2) Open the corresponding module: scope: "cell " in the  CDF layer "base"

    3) enable " parse as number" option 

    4) Open ADE XL and add the Design Varibles you have included in your  Verilog AMS Code

    And that should do the job.

     

    Bye Bye 

     

    Ps: This is how the cdfDump file looks like now:

      cdfCreateParam( cdfId
            ?name           "Fo"
            ?prompt         "Fo"
            ?defValue       "4.5e+07"
            ?type           "string"
            ?display        "artParameterInToolDisplay('Fo)"
            ?parseAsNumber  "yes"
            ?parseAsCEL     "yes"
