  • Pre-synthesis test point insertion
    Patent number: 6311317
    Abstract: A method of and system for inserting test points within an integrated circuit design. According to the present invention, test points are inserted early in the electronic design process and prior to logic synthesis such that the problem of design constraint violation can be avoided. One embodiment of the present invention includes the computer implemented steps of receiving an unmapped netlist of an integrated circuit design, and receiving from an external source, data that indicates the location and the desired functionality of the test point to be inserted. Thereafter, the present invention inserts a generic test point circuit at the indicated location and generates a modified unmapped netlist. Subsequently, the present invention performs a logic synthesis process on the modified unmapped netlist where the generic test point circuit is degenerated into an actual test point circuit for performing the desired functionality.
