经过查找资料,在tessent atpg gd文件中找到了一些参考,在analyze and insert TP in a post_scan design中,有提到,使用已有扫描链的电路,需要添加两个dofile,原文如下:
a:Load the setup_constraints.dofile, which has all the clock definitions, input constraints, and other parameters affecting the setup of the design in test mode.
b:Read in the scan_chains.do file that describes the scan chains that are already stitched in the design.
setup_constraints.dofile这个dofile我很好理解,后面这个描述扫描链的dofile我不清楚,找了好几天也没有结果,想来请教一下
