CES - Assign a value to a variable

Question asked by lary.e on Sep 27, 2009

Do I miss something?

I defined a variable named "somelength"

On pin-pair "A", formula I wrote "=somelength"

On another pin-pair, "B", I use the variable in a formula like "=5000-somelength+/-100th"

The last formula is templated and used on several pin-pairs.

how can I get a violation on the first formula?

It is a definition of the value of the variable.

 

Second question about tuning.

Is it reasonable to get tuning constraints violations when the autorouter has plenty of space to tune?

 

Thanks

Lary
