Latest Patents

One of Sandip Bag's latest patents is a system and method for testing Segment Lookaside Buffer (SLB) and Translation Lookaside Buffer (TLB) cells during processor design verification and validation. This invention presents a method for re-executing test cases and modifying effective addresses, effective segment identifiers (ESIDs), and virtual segment identifiers (VSIDs) to ensure comprehensive testing of a processor's SLB and TLB cells. The test case generator creates an initial set of effective addresses, ESIDs, and VSIDs, while the test case executor modifies these parameters during each re-execution to thoroughly test each bit within the SLB and TLB entries.

Another significant patent by Sandip Bag is a system and method for increasing error checking performance by calculating CRC (Cyclic Redundancy Check) calculations after multiple test patterns for processor design verification and validation. This invention aims to reduce verification time by sharing memory between multiple test patterns and performing results checking after each test pattern executes at least once. The test pattern generator creates multiple sets of test patterns, which are executed by corresponding threads or processors. After all test patterns have been executed, a memory error detection check is performed to ensure the system's functionality, allowing for more efficient testing.
