Dear all
In the current simulation, I meet one problem. When there is short transmission
line in the netlist, the simulation is very slow.
For example, in my netlist, there is the following sentence
wline_trunk01 node1 vss rseries1 vss rlgcfile=sline_50.rlgc n=1 l=1800mil
wline_trunk02 rseries2 vss stub_01 vss rlgcfile=sline_50.rlgc n=1 l=6500mil
wline_trunk03 stub_01 vss stub_02 vss rlgcfile=sline_50.rlgc n=1 l=200mil
wline_pull stub_02 vss pull vss rlgcfile=sline_50.rlgc n=1 l=200mil
wline_stub01 nd_out_01a vss nd_out_01 vss rlgcfile=sline_50.rlgc n=1 l=200mil
wline_stub02 nd_out_02a vss nd_out_02 vss rlgcfile=sline_50.rlgc n=1 l=200mil
If the length of the wline_stub02 is set as 10mil, the simulation would become
very slow. Could anybody tell me the reason.
Best Regards
