      The development of very large scale integration circuits (VLSIs) on the base of basic matrix chips (BMC) is a complex process involving a VLSI manufactures and its customer. VLSI customer is to develop schematic diagrams within the basis of BMC library elements and tests for production control over the integrated curcuits manufactured. The development of schematic diagrams and tests is usually carried out under the environment of the specialized system of computer-aided designing (CAD). Such system application for a large amount of VLSIs is not efficient.
      The paper considers VLSI CADs constructed from components of widely used lowcost computer-aided design systems. PCAD designing system and FLY DIGITAL DESIGN+ system of logical modeling are used as the CAD’s base. Additional program tools have been developed during VLSI CADs designing which solve the two main problems:
      - increase in modeling accuracy;
      - providing a possibility to prepare test sequences for control over the integrated circuits manufactured.
      Using this CAD system three types of VLSIs have been designed for the system of interprocessor communications in MP-3 multiprocessor, that have been successfully manufactured and tested.
