The MIMIC software package, written as FORTRAN overlay programs, executes input statements of the mathematical model in six consecutive passes. Simulation programs written in MIMIC are compiled rather than interpreted. The core of the simulation package is a variable step numerical integrator of fourth-order Runge-Kutta method. Many useful functions related to electrical circuit elements exist besides some mathematical functions found in most scientific programming languages. There is no need to sort the statements in order of dependencies of the variables, since MIMIC does it internally.
Parts of the software organized in overlays are:

Expression-oriented programming languages
An expression-oriented programming language is a programming language where every construction is an expression and thus yields a value. The typical exceptions are macro definitions, preprocessor commands, and declarations, which expression-oriented languages often treat as statements rather than...

In mathematics, a nonlinear system is one that does not satisfy the superposition principle, or one whose output is not directly proportional to its input; a linear system fulfills these conditions. In other words, a nonlinear system is any problem where the variable to be solved for cannot be...

The MIMIC software package, written as FORTRAN overlay programs, executes input statements of the mathematical model in six consecutive passes. Simulation programs written in MIMIC are compiled rather than interpreted. The core of the simulation package is a variable step numerical integrator of fourth-order Runge-Kutta method. Many useful functions related to electrical circuit elements exist besides some mathematical functions found in most scientific programming languages. There is no need to sort the statements in order of dependencies of the variables, since MIMIC does it internally.
Parts of the software organized in overlays are:
- MIMIN (input)– reads in user simulation program and data,
- MIMCO (compiler) – compiles the user program and creates an in-core array of instructions,
- MIMSO (sort)– sorts the instructions array after dependencies of variables,
- MIMAS (assembler) – converts the BCDBCDBCD may refer to:* Binary coded decimal, representation of individual decimal digits in binary.* Bad Conduct Discharge, a form of discharge from US military service* Barrels per calendar day, a unit for measuring output of oil refineries...
