ISIM Language

Full details of the ISlM digital simulation programming language can be found in the appendix, and by reference to the ISIM programs associated with the simulation examples of Chapter 5. 

All the above changes are easily implementable in dynamic simulations, using ISIM and other digital simulation languages. The forms of response obtained differ in form, depending upon the system characteristics and can be demonstrated in the various ISIM simulation examples. The response characteristics of real systems are, however, more complex. In order to be able to explain such phenomena, it is necessary to first examine the responses of simple systems, using the concept of the simple, step-change disturbance. 

Non-linear parameter estimation is far from a trivial task, even though it is greatly simplified by the availability of user-friendly program packages such as a) SIMUSOLV (Steiner et al., 1986), b) ESL, c) a set of BASIC programs (supplied with the book of Nash and Walker-Smith, 1987) or d) by mathematical software (MATLAB). ISIM itself does not supply these advanced features, but ISIM programs can easily be translated into other more powerful languages. 

The included diskette contains the ISIM simulation language as well as simulation examples. It can be run on all DOS-PC s. 

The ISIM software is made available only for the purposes described in this book, and its features are restricted to the.se examples. An advanced simulation language, ESL, is highly recommended and is also available. Users wishing to purchase the latest version of the ISIM or ESL should contact ISIM International Simulation directly. User manuals for ISIM may also be purchased for 40 from ISIM International Simulation. 

Nearly all of the F.21.P platform hardware resources are used by at least one exercise. Most popular resources are alphanumeric LCD, LEDs, input switches, input buttons. Multimedia Card interface, and Marvell Armada extension board. From the software tools, the most used tools by exercises are VHDL source code editor, Xilinx ISE tool chain, and Xilinx Isim simulator. It is interesting to note that VHDL is the language of choice for digital system design in partner institutions, even though Verilog is just as widely used in industry and academia. The...
