Issue with Cadence analog value fetch functions
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

You should not need to use -loadvpi. I suspect you're probably using an old version of the simulator maybe? What version are you using? (what does "irun -version" return).

Regards,

Andrew.
