gel
What Gel is a new high level hardware scripting language that makes it convenient to specify hardware designs and permits the construction of paradigm specific libraries. It features a rich set of data types, is extremely succinct, and is expression oriented. Modules are described as functions and composed through function calls. Types and bit widths are inferred automatically and functions are automatically folded and common subexpressions are identified. A compiler has been developed that translates Gel to Verilog and a number of applications have been developed.
