Automatisk routing af komplekse digitale og mixed-signal kredsløb

Synopsys has announced advances in its Galaxy Implementation Platform with the introduction of Galaxy Custom Router technology. The new Galaxy Custom Router provides automatic routing for complex high speed digital and mixed signals nets that require carefully crafted, high quality layouts, such as shielded buses or nets, differential pairs, twisted pairs and matched resistance and capacitance (RC) routing.

This new shape based router delivers 2 to 5X productivity improvements over manual efforts and is ready for use with advanced designs by offering support for 20nm and smaller process technology design rules, including double patterning.

Galaxy Custom Router enables the IC Compiler solution users to create high quality routing patterns for difficult routing tasks, such as differential pair routing, shielded routing (including bus and differential pair shielding), matched RC routing, river routing and point to point coaxial routing. Users can pre-route sensitive nets using a rich set of custom routing options and continue with IC Compiler to complete the physical implementation.

Galaxy Custom Router supports advanced process technology nodes, including 20nm. For example, it automatically creates colorable routing patterns. It also supports variable track grids - a requirement for some advanced node processes. Galaxy Custom Router adheres to constraints specified in IC Compiler, including default and non-default design rules, routing grids, route keep outs, route blockages and route guides.

- Increasingly, mixed signal and digital designs require hand crafted quality routing for sensitive analogue and high speed digital signals, says Paul Lo, senior vice president and general manager of the Synopsys Analogue /Mixed Signal Group.

- Galaxy Custom Router is a key technology for addressing this need, and a significant milestone toward realising our vision of a unified solution for digital and custom system on chip design.
