Question on using RLOC_RANGE

MM,

I am asking the experts here. Will post their reply soon,

Austin

Thanks Austin...

MM,

The expert did not understand your question.

Perhaps you could supply me with more details while he asks me to ask you some questions?

One comment I received was that we thought it took a minimum of four DSPs to do what you want, and that was confusing to us (as we saw three in your post?).

MM,

Here it is:

"If he wants to use RLOC_RANGE he has to create a set (using U_SET for example) and place the RLOC_RANGE attribute on a single member of the set, not on all of them as he is doing now with a wildcard.

A simpler alternative would be to use independent LOC constraints on the three DSP48s.:

I hope this helps.

Austin

aust> MM,

Thanks again Austin. Obviously I wasn't using the RLOC_RANGE correctly... I have now put independent RLOCs on each of the DSP48s. I still think however that there has to be an easier (and less restrictive in terms of relative component order) way to tell the tools to place things close together. I believe the COMPRESS attribute is supposed to do just that but according to the docs it doesn't work for DSP48s.

MM,

You are welcome.

Your comments about the placement are noted. There is a lot of work going on in just this area (of best placement, easiest way to control..etc.).
