Title: Issue with Cadence analog value fetch functions Post by sgh2050 on Sep 21st, 2017, 6:18am Hi All, Cadence provides following analog value fetch functions $cds_analog_is_valid() $cds_get_analog_value() I have these functions in a SystemVerilog module. I am using $cds_analog_is_valid first to check a signal is a analog signal and then $cds_get_analog_value to get it as real number. When i use these functions I get the error message. ncsim: *E, MSSYSTF ..... User Defined system task or function ($cds_analog_is_valid) registered during elaboration and used within the simulation has not been registered during simulation ncsim: *E, MSSYSTF ..... User Defined system task or function ($cds_get_analog_value) registered during elaboration and used within the simulation has not been registered during simulation Let me know if you have faced similar issue and how you solved it. I guess Cadence VPI routines with these functions is not getting loaded. Is there a way, I can load these these using -loadvpi * BR & TIA |
