acc_fetch_value (%v)

[paz]

acc_fetch_value(net_handle, "%v", null);

Which values it can return?

my experience shows that it can return: St0,St1,We0,We1,StX,WeX, HiZ .

Are there more options for the output?


Thanks,
Paz

There are something like 120 strength/value combinations it can return.
You are unlikely to see most of them unless you are using things like
trireg nets and resistive MOS switch primitives. Verilog has 8 drive
strengths and can represent any contiguous uncertain value range
between two strength/value combinations. I would suggest that you find
a Verilog LRM or textbook that describes the strength/value system in
Verilog.
