Abstract : The VHSIC Hardware Description language (VHDL) is an advanced hardware description language (HDL) that supports the design and documentation of digital systems. The Continuous Acquisition and Life-cycle Support (CALS) program has designated VHDL as a CALS 'building block data format.' The purpose of this study is to analyze the need for VHDL testing to support compliance to the VHDL Standard, and to determine appropriate Air Force CALS Test Bed (AFCTB) activities to support VHDL Standard application in the DoD. VHDL is a recognized industry standard and is accepted by DoD and other Federal agencies. It enables designers to model, simulate, and test systems from requirements to detailed designs. Models are used directly to manufacture hardware. VHDL also completely documents digital designs in completely technology independent data that can be used to reprocure or retrofit systems long after an original integrated circuit technology is no longer available. VHDL data, used to reprocure and retrofit weapon system electronics, offers inestimable potential for life cycle savings as weapon life spans generations of technologies. The design automation industry has and continues to develop numerous VHDL design and support tool developments. The electronic design industry is rapidly moving to VHDL. Several DoD programs, including the F-22, are using VHDL for digital system developments. Although there is an accepted industry standard, there is no test capability to assure the industry tools comply with the standard, or that VHDL data is in compliance. Therein lies a problem for the DoD. The DoD needs the assurance that acquired weapon system data will be usable for future reprocurements or redesigns. There is a need for VHDL tool compliance testing as well as VHDL data testing.
