White Paper: Can You Have It All? Evaluating FPGA-Based Prototyping Systems

Michael Posner, Product Manager FPGA-based prototyping solutions (Synopsys, Inc.)
RTL simulation is no longer capable of providing all of the verification required for today's complex designs. Modern systems are a complex mixture of hardware and software, digital and analog, and the boundaries of the system are often difficult to define.

SoftScan uses a unique GPU-based algorithm that performs high-resolution scan conversion on large polar stores with minimal CPU overhead and requires no specialized hardware.
You’ll watch eye diagrams demonstrating very low jitter, and how pre-emphasis and equalization improve signal integrity and allow for very long traces.
In the rapidly growing network market segments that leverage AdvancedTCA and MicroTCA-based systems, the standards bodies and industry consortia agree that Carrier Grade Linux is the operating system of choice.
