Possible use of optimization tool in SPECTRE/211 using SPICE

AndyWangsh

Greeting,

I previously worked with hspice in synopsis with their good optimization tool.

However, it seems like there is no such counterpart in the spice supported by SPECTRE/211.

It would be great if there is an example of it in SPICE.

If I need to switch to other tools, I would prefer script-based workflow rather than GUI based. 

Thanks in advance.

    This is absolutely possible with Spectre using the Measurement Description Language (MDL). Details can be found in the Spectre Circuit Simulator Measurement Description Language User Guide and Reference manual which can be found in your SPECTRE installation at <SPECTREinstDir>/doc/mdlref/mdlref.pdf - look at the search and mvarsearch statements. 

    There's also a tutorial with examples of using this in the SPECTRE installation at <SPECTREinstDir>/tools/spectre/examples/MDL_workshop - there's a PDF and a gzipped tar file containing some example files (the PDF has the instructions).

    There is some support for reading the HSPICE syntax for optimization using .MEASURE statements and internally using MDL to implement that, but we don't document that syntax and personally I find the MDL syntax a lot more expressive than the .MEASURE statement approach - so you will hopefully find that easier to understand, control and use.

    Regards,

    Andrew
