SCHEDULE A

LICENSED PRODUCT

Licensed Product consists of a Design for Testability tool suite which includes the following tools delivered in source code form:

SCANCHEK compiles a circuit description from Verilog structural netlists and checks the logic for compliance to a set of Scan rules. It also extracts the combinational logic driven by the scan chain as well as a description of the Scan chain connections and pin types.

Automatic Test Pattern Generator (ATPG) generates and/or evaluates a set of test vectors for the faults in the combinational part of the logic of a circuit. ATPG applies random patterns to detect most faults and switches to deterministic algorithms to find the remaining one. Optionally, the random patterns can be generated by a Linear-Feedback Shift-Register (LFSR) and the expected responses for the circuit are compressed and expressed in terms of a 32-bit signature.

SEQUENCE populates a test pattern data base with the test patterns generated by ATPG for the combinational portion of the circuit. SEQUENCE automatically adds generic test patterns for the scan chain itself and asynchronous set/reset pins, if applicable.
