SIMPLIS is a computer software package specifically designed for the simulation and analysis of switching power supplies. In a typical switching power system, the transistors and the diodes function as switches, allowing the system to be characterized by a cyclical sequence of linear circuit topologies. By taking advantage of the repetitive piecewise-linear structure of such systems, SIMPLIS is able to perform the simulation in an efficient and accurate manner. In order to avoid potential problems caused by simple syntax errors, SIMPLIS automatically checks the syntax of the input file provided by the user. If syntax errors are detected in the input file, error messages are recorded in a file for the user to inspect and correct the errors. This feature...

Calibre® is the overwhelming market share leader and the industry standard for IC physical verification, due to the outstanding performance, accuracy and reliability of Calibre products. Over the last two years, Calibre nmDRC™ has reduced average DRC runtime by a factor of five, while Calibre\’s innovative Hyperscaling and MTFlex™ technologies have cut memory requirements in half. Calibre nmDRC also reduced overall cycle time with incremental DRC, which allows designers to make DRC runs in parallel. As DRC violations are reported, designers can immediately fix and recheck just the affected areas, while the initial DRC run continues. To handle complex and multi-variate, multi-dimensional checks that are not adequately addressed by traditional design rules, Calibre nmDRC\’s equation-based DRC (eqDRC) capability enables designers...

SymXpertTM is a powerful symbol creation tool that automates the symbol creation process by eliminating manual data entry, simplifying pin data validation, and standardizing symbol generation through the use of ECAD-neutral templates. SymXpert\’s intelligent content extraction technology speeds up the symbol creation process by a factor of 8 – 24 times, reduces design bottlenecks, eliminates opportunities for errors that can cause downstream manufacturing problems, and frees up design resources for more critical design tasks. As large-pin-count components are more frequently used in PCB designs, the creation of schematic symbols for new parts has become increasingly time consuming and error prone. Data for hundreds or even thousands of pins must be manually entered into a schematic capture program, painstakingly checked for...
