Hardware/Software Codesign and Ptolemy Today
In Ptolemy 0.7, the following domains
have elements of Hardware/Software Codesign:
Thor
The Thor domain was used in Ptolemy for hardware/software codesign.
Like the DE domain, the Thor domain was event-driven. However, it was
specialized to register-transfer level simulation of digital
circuits. It was based on the Thor simulator developed at Stanford,
which in turn was based on a simulation kernel developed at the
University of Colorado. The domain was written by Suengjun Lee. Its
capabilities were similar to a variety of commercial circuit
simulators. The Thor domain was based on very old circuit simulation
technology. Contemporary equivalents include VHDL and Verilog
simulators. The VHDL domains thus replace Thor, at least in part,
although currently the star library is not as rich.
Ptolemy 0.5.2 was the last release that included the Thor domain.
