Ada Used in Integrated
Circuits Industrial Design
Created in 1985, Dolphin Integration is a design center for integrated circuits renowned for the quality of its contributions to VLSI-ASIC's (Very Large Scale Integrated-Application Specific Integrated Circuits). In order to insure the reliable and inexpensive design of Circuitware, Dolphin Integration developed the Graphical Dolphin Solution (GDS) compiler with the Alsys Ada environment.
The GDS compiler is a true compiler. It compiles high-level, parameterized schematics, or parameterized layout requirements for a given macrocell, into low-level placement orders of microcells and routing orders of interconnections. Providing the control of automatic layout for repetitive circuitware upon specified structural parameters, it is a tool to develop circuitware generators. Powerful generators, from the most classical ones (RAM, ROM, PLA), to intricate analog cell generators (BANDGAP) and datapath generators (SPOT, ALEAS), have been developed from the GDS library. Such generators are Ada programs with parameters to instantiate modules (that is to say, their GDS-2 data base and their VHDL description) upon parameter selection.
"While many such development tools for module generators are offered in a C-like or Lisp-like language (SKILL for example), our GDS compiler has been developed with Ada, mostly inspired by the modularity of VLSI", explains Louis Zangara, Microelectronic Services Manager. The development of generators requires the capability to handle large applications (a datapath generator takes 18,000 lines of Ada) and parallelisms.
Satisfied with Performance
Very satisfied with the performance of the Ada language, the Dolphin Integration team is now looking forward to further development opportunities that will employ them both. With the recent switch from Sun View to OSF Motif, the current GDS graphical interface will soon be ported to and modified on new platforms. In addition, plans to port this application to HP platforms are in process.
