[SI-LIST] Re: Bus contention between FPGA and ZBT

Any simulator that lets you set multiple sources active can do this.  This
includes all "flavors" of SPICE, VHDL-AMS & Verilog-AMS, as well as some of
the SI tools.  The only "physics" requirement is that the sources not be
shorted together; they must be separated by a transmission line or other
element.

If the sources are separated by a transmission line, they might need to be
at the same initial voltage for DC convergence at the beginning of the
simulation.

Best regards,
Lynne

Um, SPICE?

What I can't understand about new-and-improved simulators, is the lost
capabilities that we have enjoyed for decades.
