Setting Up the Boundary Scan Specification Boundary Scan Synthesis Resetting the State of BSDArchitect At times, you may find it necessary to disregard all the commands you have entered and start over from the beginning. The Reset State command lets you do this. The effect of this command is to reset all the command arguments and values to their default values, which is equivalent to exiting BSDArchitect and reinvoking on the same design. BSDArchitect allows only one synthesis run per session--unless you issue the Reset State command to reset the tool back to its system defaults. Exiting the Tool To end a BSDArchitect session, enter: BSDA> exit If you have generated circuitry that you have not saved, the tool will prompt you as to whether or not to save the information. Setting Up the Boundary Scan Specification The boundary scan specification consists of a set of commands that customize your particular boundary scan implementation. You enter these commands after you invoke BSDArchitect. You can either enter commands interactively at the BSDA> prompt, or you can store the setup commands in a file and run it using the Dofile command. You have two choices for setting up the boundary scan logic: using system defaults, or customizing the boundary scan architecture. If you choose to use the system defaults, BSDArchitect requires no prior setup. You just execute the boundary scan insertion. If you need to set up special features in the boundary scan architecture, you can specify the desired options in a dofile. “Boundary Scan Customizations” on page 7-23 describes how to use a dofile. Another option for customizing the architecture is to modify the BSDL file produced by BSDArchitect. 7-20 ASIC/IC Design-for-Test Process Guide, V8.6_1 December 1997
