Advantages of VHDL
• VHDL has a portable design data that is also known as protect investment. This protect investment is vital especially in realizing the quality of the design.
• There is technology and independency in tool usage. As much as this is important, the use of FPGA feature may not be well used. The independency is due to the high level of description.
• The designer does not have to be omnibus as it has to remember all the details of the ASIC vendor.
• ATPG is used for ASICs. This means that, there is a test generation and an automatic synthesis.
• The language needs to be of big breadth so as to allow only one language to be used in the entire process of designing (Lipsett, Schaefer, & Ussery, 1989). A single VHDL designer is able to design and stimulate an entire system on various description ...view middle of the document...
This makes the designing time much shorter thus makes the process quit productive and competitive.
• The designer is able to think on the design concept more than the level of connecting component. This allows the designer to work on the Register Transfer and other behavioral levels. This allows the language to become more productive and much useful in the market.
• The design can be re used. Due to its high level in terms of quality, its technology is so much independent and it can be used in some cases to generate descriptions that are on a lower level (Salcic, 1998). High level technologies can be transformed into new technologies and re used again.
• The quality of the design is so much improved and the user can easily modify his description that is high leveled and explore a much larger solution space (Salcic, 1998). There are other tools that will however generate other solutions. If all the properties above are combined, a designer will obtain a high quality design so easily.
• Design Exchange. VHDL is seen to be standard and as a result, it is guaranteed to operate on any system and abide by the standards (Salcic, 1998). This implies that, if a model has been developed on one location, it has the capability to operate on several other locations and come up with the same expected results.
• Larger scale design and re use: The VHDL was modeled on a philosophy that is quit similar to that of the modern programming languages. The design composition is just the same as the descriptive capabilities (Lipsett, Schaefer, & Ussery, 1989). This is vital especially when it comes to the development of larger designs and will be produced by different people. The design may vary but the operation and the process that will realize the results will be the same.
