Microsoft patents chip testing method using JTAG for design verification
Microsoft describes a method for testing chips by creating a database of internal settings and converting test instructions into JTAG commands. These commands are then sent to the chip to check if its various parts work as intended.
In the filing’s own words
The described technology provides a method including generating a register database, wherein the register database is configured to store one or more parameters of a plurality of registers, the plurality of registers representing the registers for a plurality of functional components on a system on chip (SoC), receiving a design verification flow for verifying one or more of the plurality of functional components on the SOC, generating a design verification script based on design verification flow, converting the design verification script into a series of JTAG transactions, and executing the series of JTAG transactions using a JTAG transactor.
What exactly they claim (claim 1)
1. A method, comprising: generating a register database, wherein the register database is configured to store one or more parameters of a plurality of registers, the plurality of registers representing the registers for a plurality of functional components on a system on chip (SoC); receiving a design verification flow for verifying one or more of the plurality of functional components on the SOC; generating a design verification script based on design verification flow; converting the design verification script into a series of JTAG transactions; and executing the series of JTAG transactions using a JTAG transactor.
