What you can do (and I’ve seen it done) is define verilog modules that provide the functions of the IC and use that in their designs. I’ve seen at least two interesting classic computer recreations using this approach (re-implemenation of the CADR lisp machine in verilog and an IBM 360/30 in verilog).
ROMs are easy (just instantiate a lookup table). PLCs are just combinatorial equations which are relatively easy with the verilog “assign” statement.
