I. problem
when quartus is used to design 4 frequency divider based on D trigger, the following errors occur in waveform simulation:
Error: Waveform2.vwf.vt(30): near ",": syntax error, unexpected ','
# ** Error: D:/Quartus/modelsim_ase/win32aloem/vlog failed.
# Executing ONERROR command at macro ./D4.do line 4
Error.
II. Solution
in the schematic design, my input and output ports are named input and output respectively. That’s the mistake. We just have to name it something else. For example: CLKIN, out. Then recompile and no error will be reported during simulation. The correct simulation diagram is as follows:
