Pulsic will introduce a place-and-route implementation solution at DAC this year, including Unity Analog Router, Unity Custom Digital Router, and Unity Custom Digital Placer.
Analog and custom digital designs continue to grow in size and complexity, targeting smaller process geometries with an ever-increasing number of associated process design rules and constraints. These pressures on the labor-intensive design process are accompanied by tighter time-to-market windows and an uncompromising need for quality of results.
At the same time, optimal place-and-route results for analog and custom digital are dependent on each designer's skill and experience doing manual design or working around limitations in tools not designed for custom digital. Pulsic believes that the results from existing place-and-route solutions are usually inferior to those that an experienced designer can produce manually, so the pressure on designers' expertise has mandated a variety of manual approaches. Yet manual approaches cannot scale for large, complex designs and still meet the needed time and quality goals.
The Pulsic Implementation Solution
Unity Analog Router provides layout designers with a guided flow that enables them to complete routing using a style that mimics a manual transistor layout approach. It incorporates analog-specific features that address the unique needs of analog routing. Pulsic claims that results are equivalent to hand-crafted results, with 100% routing completion that is design rule check/ layout vs. schematic (DRC/LVS) correct.
Unity Custom Digital Router is for routing of custom digital design. Comprised of an integrated suite of shape-based routing technologies, Unity Custom Digital Router encompasses hundreds of specialized utilities that work together on the same shape-based data model to give custom digital design teams precise, handcrafted quality results with automated speed.
Unity Custom Digital Placer enables placing of digital designs manually in a layout editor by combining placement technologies that enable automatic creation of hand-crafted, precise results. Based on the familiar row-based placement concept, Unity Custom Digital Placer includes a cell-alignment capability that enables placement of non-standard cells while conforming to design rules and constraints. Hierarchical clustering technology ensures strict pseudo-hierarchical placement topologies, which enables optimization of routing resources and ensures that routing estimates used in simulation-driven flows remain relevant throughout layout. Pre-route-aware placement optimizes the placement for pre-routed critical signals in top-down methodologies.Brian Bailey
