After reading the chapter 3 and chapter 4 in this excellent book, I want to simulate some examples. However, I can't make them work on my computer . For example, the VCO in chapter 3,
(1) I make a new cellview with verilogAmsText type, then fill it with the VCO code and make a symbol.
(2) After that, build a testbench in schematic, just connect a vdc to the input of VCO.
(3) Then config, vdc with spectre; vco with verilogams; testbench with schematic;
(4) simulate in ADE with config view with tran response . choose ams simulator and OSS run option.
Then, irun err as following:
ncelab: *E,CUVDNF (./netlist.vams,23|28): Could not determine discipline for this expression .
vsource #(.dc(500.0m), .type("dc")) V0 (net1, cds_globals.\gnd! );
Could I attach vdc to the input? If not, how to test the vco or other examples then?
Thanks.
Regards.
