This article explains how a sequential always block in Verilog code is interpreted by a Synthesis tool to determine the clock and any asynchronous control signals, along with their active values/polarity.
The Multirate Ethernet MAC (MRMAC) provides high-performance, low latency Ethernet ports supporting a wide range of customization and statistics gathering. The MRMAC includes a variety of new features and design flows that enable seamless rate change, statistics management and integration with the GT blocks.
This blog is intended to help customers with 100G Ethernet (CMAC) hard block or soft 10G/25G/40G or 50G Ethernet IP core experience to design efficiently with Versal™ MRMAC. The blog will cover key differences between the UltraScale+ and Versal IP including:
AXI Stream Interface for Packet Data
New MRMAC Flex Port Feature
Statistics and Management
1588 PTP Support
Design Flow Considerations
Getting Started with the Versal MRMAC Example Design
