Example of rule check violation: critical net too close to I/O net, as revealed by EMSAT
“Measure and simulate twice, build once,” is the motto of Moss Bay EDA, the distribution arm for software developed at IBM and with other engineers, for engineers. This is also the motto of most high-end OEM companies that have come to recognize the value of simulation and measurement in getting to the correct answer faster.
Moss Bay EDA’s flagship product, EMSAT, is a rule checker that evaluates a board layout file against 16 customizable rules developed exclusively by IBM. These rules check for violations of common EMC guidelines any one of which could contribute to a compliance test failure. “It’s like having an EMC Expert sitting on your shoulder reviewing your board,” Gene Garat, founder of Moss Bay EDA says.
While many EDA companies are talking about providing a cloud computing platform for their tools, Moss Bay EDA is trying a different approach. For those interested in “kicking the tires” before buying their own copy of EMSAT, Moss Bay EDA offers a pay-as-you-go-approach. The software is downloaded and runs on your local computer, but the license resides in the cloud. Periodically the local software checks the license on the cloud and tracks usage.
A fixed fee covers all the automated PCB EMC design review necessary for a single board file. This is a low cost entry path for a small company wanting to move farther up the experience curve and add an EMC design review in their design flow. With their extensive contacts in the EMC industry, Moss Bay EDA also offers recommendations for expert EMC consultants who can not only fix a current board, but also customize EMSAT design rules for all future boards.
