Subject: Forced JTAG Insertion Especially When I Don't Want It
Hi John,
I am using Synopsys 34b. Irrespective of whether the set_port_is_pad
attribute is set or not, insert_jtag always adds JTAG_BSR for all ports
of my core block! ( And I do not want to make all my design ports to be
JTAGed!! Due to performance reasons, I want only a few of them to have
boundary scan cells and avoid it for the rest!)
I tried all options, nothing seems to work to stop this forced JTAGing.
Is it a bug with Synopsys 34b Test Compiler or what ?
Also, I would like to use my own JTAG_BSRIN instead of Synopsys JTAG.db
modules. How can I tell the Test Compiler to use it?
