VHDL is a superior RTL language over Verilog.  FORTRAN and Ada are superior parallel languages over C and the multiple C variants.  The point is that unless there is a major revolt among Embedded Programmers we are stuck with C and SystemC.  Catapult C, coming from the C side, and Forte, coming from the SystemC side, have done the best job of meeting design engineers demands based on inferior languages.  Just as Design Compiler did for the RTL engineers.We've done a lot of ESL based tape outs over the last eight years.  Sayingthat Catapult C is a failure is like saying Design Compiler was a failurein 1994.  It ain't perfect but it's the best we've got; and it's improvingevery year.Don't blame the tools, blame the language.    - Gary Smith      Gary Smith EDA                             Santa Clara, CA
