ADE-XL doesn't pick up readic initial condition file/ How to properly pass initial condition setup into ADEXL?

Hi all,

First of all, I am using Virtuoso 6.1.7-64b.

I need to run transient corner sims for an analog circuit, and the first ADEXL run resulted

in a lot of failures due to DCOp calculation failures. I then use the spectre.ic file in one of  

the successful runs to help the failure ones by enter its path in the "readic field inside the

transient options -> Algorithms.(Method A)

When I tried to run a few failure corners after this under ADE-L, SPECTRE finished

the sims successfully. However, when I load the ADE-L with the "readic" field set,  into

ADE-XL and run the corner sims again, the previously test case corners are still failed.

It looks like ADE-XL doesn't pick up the "readic" info.

In addition, I tried method (B) as follows:

I follow the info. in this previous thread to use an alternative way to include initial condition file:

(i) ADEXL does pick up spectre.ic file 
(ii) both standalone ADE-L and ADE-XL both 
read in the spectre.ic file, but they both failed with DC OP convergence issue

However, the same spectre.ic file when read in using method (A) above,
helps SPECTRE finished the sims properly without issues.


So the question now: how to make "readic" in method (A) above
works under ADEXL, or any workarounds?



Thanks,
Kevin.
