splitnets - split up multi-bit nets

yosys> help splitnets

splitnets [options] [selection]

This command splits multi-bit nets into single-bit nets.

-format char1[char2[char3]]

the first char is inserted between the net name and the bit index, the
second char is appended to the netname. e.g. -format () creates net
names like 'mysignal(42)'. the 3rd character is the range separation
character when creating multi-bit wires. the default is '[]:'.

-ports

also split module ports. per default only internal signals are split.

-driver

don't blindly split nets in individual bits. instead look at the driver
and split nets so that no driver drives only part of a net.
