Accelerating Simulation Of PCIe Controllers For DMA Applications


For memory-intensive and high-performance computing, direct memory access (DMA) is indispensable. A typical DMA operation in PCI Express (PCIe) entails the transfer of data from the system memory to end point devices using a point-to-point PCIe bus to reduce latency and increase memory access throughput between the CPU and the device. Verification of DMA engines is concentrated on the data t... » read more

How UVM Callbacks Simplify Assertion Validation


By Akshay Sarup and Mark Olen Assertions bring immediate benefits to the whole design and verification cycle; thus any challenges engineers face in coding and testing them are worth resolving. When a large number of assertions are to be validated, callbacks save time by eliminating the need to code a new sequence for each scenario. Callbacks also provide more dynamic and fine-grained cont... » read more
