Generated macros uses analytical model rather than spice simulation #10

For some reason these macros were generated with the analytical model meaning that timing data and fmax in the datasheets is mostly garbage.

These macros should be generated with proper models across all corners.

I think by default it is using analytical model, unless you set analytical_delay=False.

In the log of the pre-generated macros, I see analytical model being used. But the dynamic power numbers in .lib file are much more reasonable than my self-generated version using analytical model (10 orders of magnitude larger).

Were they manually modified @mguthaus ?
