Wingpath to cease trading on 25 October 2025
From 25 October 2025 we will no longer be selling licences for our software products (ModSnmp, ModMultiSim, Modsak, ModSlaveSim, ModMaster and ModTest).
The website will remain operational until at least 2027 for reference purposes, and for the registration and transfer of product licences.

The following sections contain techniques to illustrate how to model familiar features such as timers or random number generators in ModMultiSim. The labels for some techniques may not be immediately familiar to all users, but the concepts behind them should be self-explanatory, and the simulations contain examples of some of them.
In each section, a feature, such as a type of timer or latch, has a template for a program listing in a table. Note that not all registers in a listing are necessary - the value may be computed on the fly as part of another register's statement, rather than stored in an independent register.
