====== prs2sim ======

A hierarchical ACT file can be converted into a ''.sim'' and ''.al'' file for simulation with other open-source tools like ''irsim'' or ''cosmos''. 

Since ''.sim'' files correspond to a CMOS netlist, your production rules must be directly CMOS-implementable. This means that any pull-up network must have only inverted variables, and pull-down networks must have only uninverted variables. An explanation of how the production rules are translated into a transistor-level implementation can be found in the [[language:langs:prs|prs sub-language]] documentation as well as the documentation for the [[tools:netgen|prs2net]] tool that creates a hierarchical SPICE netlist.

<code>
% prs2sim test.act test
</code>
will generate ''test.sim'' and ''test.al'' from ''test.act''. Note that ''.sim'' files use ''/'' as the sub-circuit separator, and so ''prs2sim'' follows this convention.
