Negative Slack

ags1 over 8 years ago

I have a design (an IP) which is working fine with ZC706 but the same design is giving me a negative slack problem when used with PicoZed.

Please let me know the difference between the two on functional level.

If both devices have kintex fabric (ie. 7030 versus 7045), another difference may be related to speed grade:
- the ZC706 has a Zynq-7045 device with -2 speed grade (mid)
- the PicoZed 7030 has a Zynq-7030 device with -1 speed grade (slowest)

Mario.
