Targeting engineers developing PCIe® Gen3 systems, U4305B provides PCIe test tools for validating Gen1, Gen2, and Gen3 operation for all lane widths up to x16. Tools address such PCIe development needs as providing means of testing technologies such as NVMe (Non-Volatile Memory Express) and L1 substate operation. Available LTSSM test package lets engineers perform link negotiation testing and verify PCIe state transitions as well as validate state timeouts.
