JESD204 Verification IP


Comcores has a solid track record of delivering JESD204B and JESD204C solutions, to support the IPs we offer the verification IP for JESD204, which supports both the JESD204B and JESD204C version. Furthermore, it will support JESD204D (once the standard is published). The JESD204 Verification IP provides an advanced and efficient solution for verifying and debugging these standards in a UVM simulation environment.

The verification IP helps reduce time to test, accelerate verification process and ensures a high quality for the end-product. Comcores JESD204 VIP is prepared for seamless functionality on all major simulators with UVM support.
