ModLyng is a modern, powerful tool which helps you to create and maintain AMS models. It does not matter if you are new to the world of modeling or if you are a power user with 20 years of experience. And whether you express your models via equations, symbols, or HDL code, ModLyng can help you to get it done faster and better. You can take a visual tour of ModLyng, too.

Benefit |
|---|---|
Model import |
ModLyng can read your AMS models, whether they are written in Verilog-A, Verilog-AMS, VHDL-AMS, or MAST. ModLyng understands the language and can represent the code as equations or topological symbols. You then view, edit, and debug the model using ModLyng's powerful model editors and analysis tools. There is no need to recreate the work that has gone into your models in order to bring it into and modify it with ModLyng. |
Model debug |
ModLyng has a number of tools to help you debug your models faster than ever before. Its graphical presentation lets you understand your model in ways that a plain old text simply can not. It will not let you enter invalid equation syntax, and it handles much of the linguistic overhead (e.g., variable declarations) needed for exporting the model to the HDL of your choice. It has a graphical tool to help you detect more subtle problems (e.g., discontinuities) that cause headaches when your simulations do not converge. ModLyng cross-links topological features, model parameters, and equations, to make it easier for you to follow the design complexities. |
Model export |
Once you have captured the model inside ModLyng, it automatically puts it into the language - or languages - of your choice. Of course, you can write your debugged model in the same language in which it was originally written, or generate it in the other languages that ModLyng supports, including Verilog-A/AMS, VHDL-AMS, and MAST. |
Model translation |
ModLyng can read a model written in one HDL, and then write it in another. Imagine: creating IP that you can implement across a number of languages and platforms. |
Model creation |
ModLyng makes it easy to create behavioral AMS models from scratch as part of a top-down or bottom-up design methodology. Just name your model, define the ports in the ModLyng interface editor, create and link branches in the ModLyng topology editor, and write your equations in the ModLyng equation editor. From here, you can debug, and export the model into the language of your choice. In fact, ModLyng supplies you with a set of building blocks that you simply connect into a topological view. The equations are automatically included in the model. |
Language independence |
While ModLyng generates models for all the leading analog/mixed signal HDLs, you do not need to be an expert in any of them. ModLyng’s graphical and equation-based toolset lets you focus on the design and implementation of your model. You do not need to know the syntax peculiarities of each HDL, and you spend your time doing what you do best while ModLyng takes care of the rest. |
Platform independence |
ModLyng is aimed at the leading simulation environments from Cadence, Mentor Graphics, and Synopsys. It can run them on Linux, Windows or Solaris, and you can use your existing AMS design tools. |
