Transaction Layer Packet (TLP) Architecture
This interactive environment demonstrates the design and verification of a PCI Express Transaction Layer. Explore how the RTL constructs packets, how the Testbench verifies them, and analyze the efficiency of different transaction types. Use the tools below to generate RTL parameters and run virtual simulations.
