The created simulation language TKSL/386 is a very powerful computing tool for finding accurate numerical solutions of differential equations. The next version of the simulation language TKSL/ORCAD is based on a graphic interface. The graphic interface transforms a graphic representation (graphic symbols for describing real-existing systems) into an equivalent textual representation. The graphic editor that has been chosen is a part of a system ORCAD .
The analogue diagram (Fig.18.1) solving the system of equations (53),(54),(55) is well-known in the theory of analogue and hybrid computers.
y1'= z y1(0)=0 (53) z' = y2 z(0)=2 (54) y2 =-y1. (55)
The analogue diagram (Fig.18.1)
consists of two integrators (with predefined initial
conditions) and one invertor. The integrators and invertor are
among the basic elements of a specially created library of the
simulation language TKSL/ORCAD ( the library consists of integrators,
invertors, summers, function generators, multipliers, dividers,
blocks of transfer functions, nonlinear blocks and blocks defined
by users). When the simulation language
TKSL/ORCAD is used, the diagram (Fig.18.1) must be plotted on the screen
(according to the rules of the system ORCAD). After the
program is started, a source code identical with the source
code of the language TKSL/386 is
automatically generated.
