Every simulation requires a good static check to be performed to insure that,initially, the equations being simulated match those of the analysis and, subsequently, to be sure that the analog computer's patchboards remain free from wiring errors. Custom arily the static check is prepared by hand using a desk calculator, since the time required for pro gramming a "one-shot" digital program is typically not a good investment. However, by utilizing the capabilities of a suitable simulation language (such as CSMP or DSL/91), digital static checks can be made economically in less time than that required for a hand-calculated check, especially in the case of hybrid computations. Also, with a little ingenuity, the efficiency of hybrid simulation can be greatly increased by combining the static-check calculation and automatic analog setup via the simulation-language static check. (Familiarity with analog programming and the use of simulation languages is assumed.)
