Abstract
A method of configuring scan mode circuitry of an integrated circuit (IC) device includes parsing through an initial file of the scan-flops that are to be included in the scan mode circuitry. The initial file can be prepared with a synthesis tool such as Synopsys. A particular subset of scan-flops are parsed, according to an identified number to be included in each scan chain. A holding tank is created to hold each subset of scan-flops for each scan chain. Each holding tank is then used to form a scan path and to stitch the corresponding scan chain. The parsing of the scan-flops into holding tanks can be performed with a c-shell script. Also, the c-shell script can be called by a Synopsys dc_shell script.
