Version 1.7 of VisualMath is ready for evaluation. This simulation and
design
software allows creation of a system using a graphical language. The
basic
data type is a matrix and the output results are presented in tabular or
plot form.
It is somewhat like the Matlab-Simulaink combination from The Mathworks.

VHDL code can be generated as output. Verilog and C code generation will
follow.
