Synthesis never ends

I created a code for cat/dog recognition using 1 process that reads from ram the picture and make calculations. I run Synthesis and completed. I run behavioral simulation and it’s all ok. After that I tried to compare the value of a variable to a threshold value in the process and set the output of my design to ‘1’. The output is mapped to an led. After doing that synthesis never ends. If I remove the if statement synthesis ends. What to do?

Re: Synthesis never ends

Hi @panayiotis95,

 

>>After doing that synthesis never ends.

What is the time that you have waited for to complete synthesis? 

Have you tried with synthesis default strategy and check?

 

Is it possible to share your testcase to evaluate it at our end? If yes, i can share the ezmove ftp through which you can share your files.

Re: Synthesis never ends

Before that was near 3-4 minutes. After that I waited 1 hour but nothing. I have the default strategies, I didn’ t change anything. You mean to send the code?

@panayiotis95

Some other people who have reported such, have accidentally done something like recursion, then ran out of memory. The way you describe you code sounds simple enough, so it may not apply, but just a thought.
