ADEXL: detecting process corners

kawan

Hello,

Is there anyway I can have a circuit block decide its output value based on the process corner selected? Details as follows:

So I set up my process corners  to go FF & SS & TYP in a ADEXL simulation.

Block A puts out a value to calibrate for the process corner, It has analog and digital circuitry inside with clocking and all te fancy stuff. But at the end of the day, the value put out feeds all other analog blocks so they can tune in to the process corner.

I can run Block A withe mixed mode sims and collect the data. So I now know the value based on the process corner.

Can I have a view for Block A that puts out the value  based on the corner that ADEXL is running its present simulation? In other words, how do I detect a process corner and act on that information.

Thanls

  • Zakir,

    Several options here. One is to use a "pre-run script" to do the calibration - or at least to look up the calibration value that you've previously found. More details are in the documentation.

    However, it might be simplest just to have a simple view (maybe Verilog-A or a simple schematic using voltage sources or whatever?) which outputs the value in whatever form you want and have the value controlled by a variable on the instance. That global variable could be added into your corner definitions so that for each corner the global variable has the value you previously captured in your mixed-signal simulations.

    Regards,

    Andrew.
