FENCE Regions

[udaymallappa]

I don't find examples for setting up FENCE region constraints. Can you help me ?

FENCE region is defined in DEF files. You may refer to ispd 2015 benchmarks for how to define region constraints.

Thanks for your quick response. I am using a bookshelf format for my testcase. Is there an easier way to define FENCE constraints, without having to using the DEF format ?

[limbo018]

Bookshelf format does not support FENCE region. You can consider convert bookshelf to LEF/DEF. There was an old tool to do that. You might be able to find other tools as well.

Hi,

I would like to ask if DreamPlace support other types of region constraints such as GUIDE, DEFAULT defined in DEF.
Thanks!

Best regards,

DREAMPLace does not support region constraints other than FENCE, we will support more region constraints in the future.
