Show CHAPTER 4 OTHER ACRE SUPPORT FOR ANALYSIS ACRE provides a compliment of support features for circuit analysis that will be explained in this chapter. These include a table interpolation utility and a general database facility. The table interpolator provides considerable assistance to circuit analysis by allowing empirical data to be referenced from a three-dimensional plot, where an equation might not be known or might be very compute intensive. The database facility employs a novel scheme to handle accumulation where the indices might be node numbers and the database might accumulate total capacitance. By making it easy to evaluate, store and express complex relationships, ACRE reduces the troubles that come with the quantity and complexity of the data flow. ACRE also has an extensive debugger and a facility for user installed functions to be linked with the language. This debugger has the notion of degrees of debugging to trace the operation of the machine at various resolutions and allows a user to localize rapidly his debugging efforts. The userdefined and user-installed functions allow a user to put his functions at the same efficiency as the installed functions, eliminating the most common complaint about an interpreted language. Between the debugger, which can expose exactly what the program is doing, and the user-defined functions, |
