![]() The free-form schematic format makes it easy to place parts into any configuration and edit them as required. A topology in a cell-based schematic is limited by the available connections within and between the cells.Ī more robust and expandable way to create a circuit schematic for simulation is to use the free-form schematic format in LineSim. Parts of the grid-based cells are filled with the desired objects to create the topology. Cell-based schematics are based on fixed cells consisting of typical placements of buffers, trace impedances, and components. ![]() LineSim provides two methods for creating routing schematics: cell-based and free-form. You configure simulations in LineSim using a schematic GUI to create connections and topologies between I/O buffers, route trace segments, and termination components. Because the process of creating and running simulations is very similar for both LineSim and BoardSim, the details of IBIS model use in LineSim applies to simulations in BoardSim. With board and routing parameters, and surrounding signal routing known, highly accurate simulations of the final fabricated PCB are possible. You select one or more nets from a board layout file and BoardSim simulates those nets in a manner similar to LineSim. Before any board routing takes place, you use LineSim to simulate “what if” scenarios that assist in creating routing rules and defining board parameters.īoardSim is a post-layout tool that you use to analyze existing board routing. The HyperLynx* software is a PCB analysis and simulation tool for high-speed designs, consisting of two products, LineSim and BoardSim. The HyperLynx* software makes it easy to integrate IBIS models into simulations. The HyperLynx* software from Mentor Graphics* is one of the most popular tools for design simulation.
