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

  • Mostafa,

    You can do that entirely in spectre. Look at the documentation for spectre's Measurement Description Language (MDL) which would allow you to implement such an optimisation within the simulator.

    There are examples in <MMSIMinstDir>/tools/spectre/examples - an MDL workshop is provided.

    Alternatively you could implement the loop around the simulator using OCEAN - this would allow you to use the same kind of measurement functions that you can use in ADE and then place an adaptive loop around the simulator, altering the values of design variables based on the results of the previous simulation.

    Best Regards,
