Question

i get an error when i do compilation.

loop with non-constant loop condition must terminate within 250 iterations

Then, i change the limit of looping constant:

set_global_assignment -name VERILOG_NON_CONSTANT_LOOP_LIMIT 512

My pc can't perform compilation and get an error as in title after changing the limit.

What should i do in order to compile it?

why do you have such a large loop? such things often dont represent real hardware.

i would like to implement a fir filter which has 300 tap. So, it needs 300 shift register by using loop to implement it.  Any idea to my problem?

if you know it's 300, why isnt it a constant loop?

altera_forum · Answer

The max tap is 300 and it is a custom fir filter.  The number of tap will changes in real time.
