Hi

I want to design traffic light controller using AHDL so I writ the code for traffic controller and for the timers and all is successful individual but when I design the circuit for all and connected to gather I have three error but I do not know how to fix it so please can some one help me and tell me what must I do.

Thank you.

This is the error.

[1] error: port "100_cnt" does not exist in macrofunction "inst20".

[2] error: quartus ii analysis & synthesis was unsuccessful. 1 error, 11 warnings.

[3] error: quartus ii full compilation was unsuccessful. 3 errors, 11 warning.

What is mean about the macrofunction.

Usually only the first error is significant to look at. In your case most probably you have named the port incorrectly when you instantiate the "inst20" entity.
