Reading from a text file in Spectre

Analogstudent

Hi all,

How can I convert the below Hspice code to something acceptable for Spectre?

************************************************************************************

 Simulator lang=spice

.Tran 100u 1m


.DATA vals LAM
+ FILE='data1'
+ idep1val=1
+ itd1val=2
.ENDDATA   ****** This is how it works in Hspice

Idep1 vdd idep1  idep1val   ***** Bias currents in my spectre netlist
Itd1  vdd itd1   itd1val  

 *********************************************************************

This is the stimulus file that I have included for my scptre simulation.  

It works fine if I just mention the reuired values like this:

Idep1 vdd idep1  100u
Itd1  vdd itd1   100p 

But I need to read these values from an extrenal file and that's where it doesn't like it.

 Is there any better way of doing this?

Your help is highly appreciated.

Regards

Mostafa

  •  Thank you very much Andrew. I was away for a couple of weeks.

     I tried the way you suggested. But I couldn't get it work.

     Here is what my file contains:

    myParams paramset {
    idep1val itd1val
    100u 100p
    }

     

    I included this file to my stimuli file as:

    simulatro lang=spectre

    include "(path)/paramset.scs"

    simulatro lang=spice

    Idep1 vdd idep1  idep1val

    Itd1  vdd  itd1     itd1val

     

    but still it complains that "unknown parameter name idep1val"

     

    What am I missing here?

     

    Thanks in advance
