Solving an implicit equation (Read 2972 times)

VerilogANovice New Member Offline Posts: 9 Mountain View	Solving an implicit equation Feb 11^th, 2007, 6:03pm Hi, Is there any way in Verilog-A to solve an implicit equation? The function I want it to peform is like "fzero" in MATLAB.

In this case they are written in fixed point form: x=f(x). Verilog-A also provided the indirect assignment statement that explicitly supports implicit formulations. -Ken
