like VHDL/verilog RTL coding tool , and can simulation simple code
I only find editC for C coding & pocketC can compiler it ..

I hope someone can tell me where can I find user define keyword
texteditor , like verilog can define "register" .. some keyword and with color font

and can simulation some RTL code .

I only find circuit simulator like SPice free source code , but I tink even Treo650
CPU can not simulation spice circuit . Have anyone have RTL simulator source C code ?
