| | Hardware description language - Wikipedia, the free encyclopedia |
 | | In electronics, a hardware description language or HDL is any language from a class of computer languages for formal description of electronic circuits. | | | An HDL is analogous to a software programming language, but with subtle differences. | | | Designing a system in HDL is generally much harder and more time consuming than writing a program that would do the same thing using a programming language like C. |

| | VHSIC hardware description language - Wikipedia, the free encyclopedia |
| | This is unlike many of the other computing languages such as BASIC, Pascal, C, or lower-level assembly language which runs at machine code level, which all run sequentially, one instruction at a time on von Neumann architectures. | | | A particular pitfall in both languages is accidentally producing transparent latches rather than D-type flip-flops as storage elements. | | | Because of this general-purpose nature, it is possible to use VHDL to write a testbench that verifies the functionality of the design using files on the host computer to define stimuli, interacts with the user, and compares results with those expected. |

| | Java Based Hardware Description Language: JHDL |
| | JHDL is a language developed with the intent of elegantly embodying the run-time reconfiguration paradigm in a commonly used (familiar) programming environment. | | | For execution, it should be possible to switch transparently from a software simulation to hardware execution on the CCM simply by changing a software switch. | | | Thus, software simulation and hardware execution are performed with the same piece of code, enabling a true codesign methodology. |

| | Simulation Speed in Hardware Description Language |
| | Compil ers for simulation languages are nothing new, of course, but the recognition tha t hardware description languages could be compiled just like general purpose sim ulation languages such as GPSS and Simula is relatively recent. | | | Up until recen tly, nearly all simulators for hardware description languages were implemented a s interpreters. | | | Using gener al-purpose computers and software simula tion has the proper functionality, but general-purpose computers increase in speed linearly, while simulation demands i ncrease exponentially. |

| | Burket said that even though "We're hoping VHDL will become the universal language, the problem resides in having models that are interoperable from tool to tool." Even within VHDL that is only rarely the case, he said. | | | Indeed, a recent challenge by Cadence Design Systems Inc. president Joseph B. Costello for EDA users to focus on a long-term goal of creating a single, unified language for top-down design is considered by some a side issue. | | | The divergence and growth of the two EDA languages has done much to exacerbate the problems users now face. |
