I try to run ams simulation with UltraSim solver a block (let's call it A) containing block (B) described as a spice netlist. Block B has several bus inputs and during elaboration I receive error message: "Vector net cannot be connected to a Spice/Spectre instance by port name". Really, netlist of block A has intstance of B: subckt_B B(.OUT(out), .IN(in[3:0])), while spice description of subcircuit B looks like .SUBCKT subckt_B OUT IN<0> IN<1> IN<2> IN<3>. I added cfg file with cell description
string prop sourcefile="path_to_file";
string prop sourcefile_opts="-auto_bus" ;
But it didn't help.
How can I run ams simulation for design, which contains spice netlist with bus ports?
What you've said sounds as if it's probably reasonable, but it's hard to tell without seeing the whole picture.
You're probably best off contacting Cadence customer support and providing the data that you're trying to simulate, and then somebody can investigate this more closely than is possible in a public forum.
