System Generator Build Times - Slow

Jump to solution

Our System Generator projects have been taking a large amount of time (nominally in excess of over 3-4 hours) to generate HDL netlists.

This is in stark contrast to similar designs taking ~45 minutes with the legacy ISE (12.4) + Sysgen (Matlab 2010a/b) tools.

We were hoping to see improvements with future releases, but is seems that the long build times continue to be prevalent.

Questions:

What options are available to help improve the build times for System Generator projects?

Could you help enlighten us on what is going on behind the newer Sysgen tool curtains that could be slowing things down?

 

Legacy Tools:

ISE 12.4 + Matlab 2010a/b w/ Windows 7 (Floating Licenses)

Current Tools:

Vivado 2018.3 + Matlab 2018a w/ Windows 10 (Floating Licenses)

We have used other tool variants with similar results.

Resource Analysis / Timing Analysis running in the background will cause long code generation times.

The above analysis triggers Vivado Synthesis or Implementation process on the design, in background to get the resource utilization or design timing reports.
