I am still new to physical synthesis and would like to ask a question. The file ARM946ES.pdef is generated automatically?

Can you please, if possible, give an example of a pdef file.

Thanks

set_scan_signal site:edaboard.com

In your script, you illustrate how to synthesis ARM946, but I want to know why not use hard core or netlist .In this method ,the only thing you do is to merge the layout. Can you tell me the reason?

thanks!
recently, I study PKS, could you provide with PKS scripts in this flow~~~
