Suppressing particular warnings

Postby CousinItt » Tue Dec 01, 2020 2:36 pm

Hi all,

I'm working with a system using clock sources with different frequencies. The nominal frequencies produced by the PLLs are close enough (within a few PPM) but I get the following warnings, for every node and every source file:
.././MSC.xn:11 Warning: XN11137 500000000Hz system frequency for node "0" could not be achived. Using 499998720Hz.
.././MSC.xn:11 Warning: XN11136 Default 100Mhz reference frequency for node "0" could not be achived. Using 99999744Hz.
Is there a way to suppress just these particular warnings?

Also note the spelling errors. That's programmers for you.

Have you tried changing the XN file to request those frequencies directly? i.e. in the <Node> tag after Oscillator="<osc freq>" add SystemFrequency="499998720Hz" ReferenceFrequency="99999744Hz"

Then you will get the exact values and it won't complain.

I hadn't tried that, but I will. Thanks for the tip!

OK those warnings have gone away. xmap still gives the following, but it's a helpful reminder in my view.
xmap: Warning: Node "0" does not have 100Mhz reference clock.
Thanks akp

Fantastic. Glad it's not spewing out a tonne of useless warnings anyway.
