Syntax error in m1_alu.v

Back to bugtracker overview.

Information:
Type :: BUG
Status :: CLOSED
Assigned to :: Fabrizio, Fazzino

Description:
I've tried to synthesize the m1_cpu with ISE and QuartusII but both tools choke with an syntax error on the same source line.

QuartusII 8.0:
Error (10170): Verilog HDL syntax error at m1_alu.v(33) near text "~|"; expecting ";"

ISE 10.1:
ERROR:HDLCompilers:26 - "../../hdl/rtl/m1_cpu/m1_alu.v" line 33 unexpected token: 'a_i'

For synthesis only I had to change the NOR operator from

a_in ~| b_in

to

~(a_in | b_in)
