Timequest: toggle synchronizer constraints?

Hi rbugalho,

After some googling... there's an issue with a setting called "Display entity name for node name".

Put simply: they (default) way get_node_info works for register names is not compatible with the filters get_pins accept.

Thanks! I'd missed that page.

But I would just live with the warnings; or suppress them.

I don't like adding stuff I shouldn't just to suppress dumb warnings.

The objective was to suppress the warnings. I am simply using TimeQuest constraints to suppress them.

I've attached the "Report Clocks" report for both method 1 (the first method I figured out) and method 2 (the method you pointed me to on the Altera site). Because method 2 strips the component names, the clock name in the "Targets" field of the report window becomes less verbose, but then that means the hierarchy to the synchronizer is a little less obvious. I don't see any particular advantage in one method over the other.

As I commented earlier, I plan to replace this synchronizer with one that uses the JTAG and core clocks directly, and I won't introduce this extra synchronizer clock, so I won't be using these TimeQuest constraints any time soon. However, this was an interesting exercise in TimeQuest syntax :)

Thanks!

Cheers,

Dave
