CEDAR LS is an interactive digital logic simulator to be used for teaching of logic design or testing simple digital designs. It features both low-level logic gates as well as high-level components, including registers and a Z80 microprocessor emulat
Pretty good all round. It does an extra something to make it excel. A component editor would be nice something like the one on LTspice. Needs scrolling sliders to compliment the method of scrolling the 'paper' Also a zoom in, out, selected and limits buttons.
Cedar Logic Simulator is very good for basic usages. However, I lack the ability to create hierarchical designs. Also, the missionary statement in the help files lower the professionalism of this software and may be considered provocative by some users.
