Video Demos on Generating X-Parameters from Circuit Level Designs
This series of four demonstration videos shows how to generate fast and accurate behavioral models based on X-parameters* generated from a circuit-level design. These models offer an ideal way for designers to share the performance of their circuit-level designs with the system design/integrator, prior to the availability of a physical prototype. Using these models, the system designer/integrator can evaluate overall system performance and conduct trade-off analysis earlier in the design cycle and much faster than if they were working with circuit-level designs. Because the X-parameter-based models are accurate and characterized over the same set of parameters that would be used to characterize the actual physical device, they also have a higher degree of confidence that the chip will work within the system the first time.
