ncsim: *E,CLNAIA: Cannot call system tasks/functions while analog engine is interactive

albas

Hi,

here is my simulation log excerpt:

ncsim> uvm_config_db -trace on
ncsim: *E,CLNAIA: Cannot call system tasks/functions while analog engine is interactive.
while executing
"call tcl_uvm_config_db 1 [cdns_get_on_off_mapping $v5] "
("-trace" arm line 1)
invoked from within
"switch -regexp -- $args {
"-dump\\s+-audit" { call tcl_uvm_config_db 0 1 }
"-dump" { call tcl_uvm_config_db 0 0 }
"-trace" { cal..."
(procedure "uvm_config_db" line 10)
invoked from within
"uvm_config_db -trace on "
ncsim>

What actually does it mean? I'm using the ultrasim solver.

  • If you look at the expanded help message, you'll see that the simulator appears to be stopped in a call to the analog model; you need to bring it back into the digital domain before you can issue this particular Tcl call.

    bash-4.1$ nchelp ncsim CLNAIA
    ncsim/CLNAIA =
    Calling system tasks/functions or C-language user defined functions
    is not supported while the analog engine is interactive. Use the
    run -sync command to advance the simulator to where the digital engine
    is active before issuing the call command.
