Hi, any suggestions for getting around this error:
<
bosje>
`ERROR: Unsupported expression on dynamic range select on signal \a`
<
bosje>
for (i = 0; i < 10; i = i + 1) begin
<
bosje>
MyModule u_temp (.x(a[i][0], .y(~a[i][1]));
<
bosje>
endgenerate
<

Guess you can't access specific bits in a for generate loop?

anyone know how to turn off synthesis optimizations?

bosje: which synth script?
<
bosje>
custom one:
<
bosje>
synth -top $top
<
bosje>
dfflibmap -liberty $lib_lib
<
bosje>
abc -liberty $lib_lib
<
lofty>
bosje: add -fast to abc
<
bosje>
what will that do?
<
lofty>
turn off synthesis optimizations
<
bosje>
awesome, thanks
<
lofty>
-fast is basically "map as-is"
<
bosje>
will it still do SAT reduction?
<
lofty>
no, but it will structual hash
<
lofty>
*structural hash
<
bosje>
Let me experiment a bit, I found that sometimes the optimizations reveal other bugs
<
bosje>
i have to basically handcraft the netlist anyway for what I am trying to do
<
lofty>
structural hashing is unlikely to cause that
