Control-Tab:

Here you define several items which control the generation of the HDL-design:


Entity-declarations-Tab (VHDL) / Parameters-Tab (Verilog):


Architecture-Declarations-Tab (VHDL)/Internal Declarations-Tab (Verilog):

The schematic is drawn in this tab.
Each graphical element can be moved by picking it with the left mouse button.
Each graphical element can be deleted by moving the mouse pointer over the element and pressing the "Delete" key.
The following graphical elements are available:

Here you can find links to 5 designs which I have created.
All designs are created by HDL-SCHEM-Editor and HDL-FSM-Editor and most of the designs are based at VHDL (only for division also Verilog is available).
By the link you will find all the needed source-files for both tools and also the generated VHDL/Verilog-files.
