New Spectre MDL output in ADE Assembler / Explorer

FAwqati

Hello,

FYI, Im using IC618 ISR16 and SPECTRE201.

It seems the output from spectre MDL control is much better/easier now, however no longer outputs into the psf "setup_meas-meas_search" or "setup_meas-meas_montecarlo" directories. Instead, it puts directly into the relevant analyses in a 'sweep' like fashion.

Apologies in advance if im not articulating my request properly. My issue is that the output format is similar to a tuple, skill list or a complex number which has 2 parts. If i perform xval() then it stays in the same structure but both parts have the same value. How do i extract the spectreMDL result but from ADE calculator measurements ? Is there a way to do this without skill ?

Many thanks,

Faisal

    Hi Faisal,

    Since SPECTRE20.1 MDL doesn't write the measurement results into PSF by default (this was done for performance reasons for the majority of MDL users who don't use with ADE). I'm not sure I would class that as "much better/easier now" - as far as I can tell nothing else has changed. Because it doesn't write into PSF but just writes text files, there isn't really good support for reading the data into ADE.

    So I would suggest going to SImulation->Options->Analog, the Misc tab and then in the Additional Arguments/Parameters field type:

    mdlpsfoutput=yes

    This will then cause MDL to write the measurement data into PSF as before, which means you can continue to use the normal access functions to retrieve it.

    One of your colleagues filed a case related to this (case 46527986, CCR 2483488). That CCR was to ensure the option was public and in a "feature file" (it is now in the latest SPECTRE20.1 ISR), with the goal that a second CCR was filed so that ADE adds the mdlpsfoutput option automatically when a recognised version of Spectre is being used that supports this option and the MDL Control Flow is being used. That second CCR hasn't been filed yet (I'll chase the AE in my team to make sure it happens).

    Noted and thanks for workaround.

    What about post processing the sweep type output thats come back and i can see in VIVA ? That seems to contain the exact information im looking for, the only problem is its structure. Is there a way to extract the x-axis points in scalar quantity using the calculator ?

    Faisal,

    I probably need to know what you're seeing. Can you log this as a case and put me on copy? Then perhaps I can take a quick look with you this afternoon.
