Information about Mimic

MIMIC, known in capitalized form only, is a former simulation computer language developed 1964 by H. E. Petersen, F. J. Sansom and L. M. Warshawsky at the Wright-Patterson AFB in Dayton, Ohio, USA. It is an expression-oriented continuous block simulation language, but capable of incorporating blocks of FORTRAN-like algebra.

MIMIC is a further development from MIDAS (Modified Integration Digital Analog Simulator), which represented analog computer design. Written completely in FORTRAN but one routine in COMPASS, and ran on Control Data supercomputers, MIMIC is capable of solving much larger simulation models.

With MIMIC, ordinary differential equations describing mathematical models in several scientific disciplines as in engineering, physics, chemistry, biology, economics and as well as in social sciences can easily be solved by numerical integration and the results of the analysis are listed or drawn in diagrams. It also enables the analysis of nonlinear dynamic conditions.

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 BCD instructions into machine-oriented code,
  • MIMEX (execute)– executes the user program by integrating,
  • MIMOUT (output)– puts out the data as a list or diagram of data.

simulation is an imitation of some real thing, state of affairs, or process. The act of simulating something generally entails representing certain key characteristics or behaviours of a selected physical or abstract system.

An expression-oriented programming language is a programming language where (nearly) every construction is an expression and yields a value. Macro definitions, preprocessor commands, and declarations are often treated as statements in expression-oriented languages.
