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.

Hi there,
Which PicoZed?
We have some that use Artix fabric (PicoZed 7010,7015,7020). We also have one that uses Kintex Fabric (PicoZed 7030).
If you are moving from a ZC706 (which uses a Zynq 7045 device), you have Kintex fabric.

The Kintex fabric is faster. If your constraints are not 100% solid, you can certainly see issues like this. If your constraints are 100%, the tools will adjust the timing paths in order to account for the differences in fabric speed.
This is especially true running a lot of asynchronous latching.
