JTAG Verification IP

Truechip's JTAG Verification IP provides an effective & efficient way to verify the components interfacing with the JTAG interface of an ASIC/FPGA or SoC.​

Truechip's JTAG VIP is fully compliant with Standard JTAG Version IEEE 1149.1-2013 JTAG specification from JEDEC. This VIP is lightweight with an easy plug-and-play interface so that there is no hit on the design time and the simulation time.
