Title: Innovations of Divyank Mittal in Integrated Circuit Testing

Introduction

Divyank Mittal is an accomplished inventor based in Uttar Pradesh, India. He has made significant contributions to the field of integrated circuit (IC) testing, holding two patents that showcase his innovative approach to enhancing circuit design verification.

Latest Patents

One of his latest patents is the "IC chip test engine." This invention selects an instrument of an IC design based on an instrument access script. The selected instrument comprises an IP block and a test data register (TDR) logically arranged upstream from the IP block. The IC chip test engine can identify a set of SIBs gating access to the selected instrument and select a scan chain for operating the set of SIBs to control access to the selected instrument. Additionally, it augments the scan chain with data to cause at least a furthest downstream SIB of the set of SIBs that gates access to the selected instrument to transition to an opened state. The IC chip test engine can also generate a set of load vectors for the scan chain to load the TDR of the selected instrument with data to apply a respective test pattern to the IP block.

Another notable patent is related to "Compacting test patterns for IJTAG test." This invention involves systems, methods, media, and other embodiments that improve the operation of test devices verifying circuit operations. One embodiment accesses a circuit design comprising a plurality of instances of one or more blocks, where each block is associated with a corresponding block test pattern comprising one or more test subpatterns. Each corresponding block test pattern is processed to identify independent test subpatterns, and then each instance is processed to identify each independent test subpattern for the circuit design. Similar types of independent test subpatterns are merged into a circuit design test pattern, ensuring that at least two of the independent test subpatterns associated with the circuit design occupy shared test cycles within the circuit design test pattern.
