Today's system-on-a-chip (SoC) designs contain more analog/mixed-signal (A/M-S) content than ever, but analog designers and device modelers continue to struggle with their development efforts.
A/M-S models are developed with HDL-dependent (hardware description language) tools that are tied to proprietary EDA platforms. This limits productivity and impedes analog-IP reuse.
Along comes Lynguent, a privately held startup, with its ModLyng integrated modeling environment. ModLyng addresses one of the main problems with A/M-S model development. What designers want to do during simulation is to debug their design, says Martin Vlach, Lynguent's CEO and founder. But what they end up doing is debugging their models and simulator.
Within the ModLyng environment, users create, maintain, debug, and translate the A/M-S models, making them reusable in other designs and across a number of target HDLs. It does this through a GUI that s independent of, yet compatible with, all major simulation environments.
ModLyng imports the model code and automatically creates a topological view of the model, interpreting the electrical equations and statements embodied in the code. Engineers can then augment and extend the models with new equations or icons representing pre-configured, or canned, behaviors (see the figure). The tool also populates a table with all of the ports and parameters in the model and generates a symbol representing the model so it can be used as a sub-element of other, larger models.
The ModLyng environment will be available in September for Linux and Windows 2000/ XP. The initial configuration, which targets the Cadence simulator, will list for $35,000 per seat for a one-year subscription license. Visit Booth 2214 at DAC for a demo.
