Now,I am using synopsys dft-compile do mbist&BSD design.
How can I integrate Mbist with bsd using JTAG control Mbist circuit?
I insert scan chain before design mbist&bsd,but ,the inserted scan chain will be removed when I insert the mbist&bsd circuit.
what's the order of doing scan,mbist and bsd.

First you must insert your MBist after this, before you insert the boundary scan you mus decalre the new instruction for the TAP and the declaration of the Data Register asociated for the Tap instruction. (in the Data Register you add de activation, status and other functions you need for you MBIST)
when you have done the configuration of the new registers you can insert the BSD.
I still have some problem.
What's the order of insert scan chain,mbist and bsd.
This is my order :
scan chain --> mbist&bsd
But,the scan chain will be removed when I insert the mbist&bsd circuit.
What can I do?
