*Error* abs: can't handle abs Monte carlo Simulation

zinal7

Hello Team,

I am getting below error while simulation monte carlo simulation, but if I do a single statistical simulation on a single run it is working fine. Ade assembler simulation reported eval error for some of the samples and when I created statistical corner with the sample name and run the single point simulation the expressions are evaluated correctly.

2023-07-28 10:07:53.654 +0100] [ERROR] [cadence.virtuoso.ade.expressionEvaluator] - point:'1' test:'clpga_final_tb_offset_correction_1'
\o Expression:'abs(value(IDC("/u_offset_trim_pga_broadband_ash_0/iout_vos_b")))'
\o because of the following error(s)
\o *Error* abs: can't handle abs(nil) {"point": 1, "testname": "clpga_final_tb_offset_correction_1", "?test": "clpga_final_tb_offset_correction_1", "?expression": "ioutb"}
\e *Error* ("plus" 0 t nil ("*Error* plus: can't handle (nil + 2.5e-06)"))

what is the difference between these two expressions? why the first one gives an eval error, while the second one works fine?

Thanks in advance, Zinal
