Is there a way to visualize/see the schematic of the chip that we are creating. You show these diagrams in the tutorials [e.g. Figure 1.6].
It would be great if there was a program that could read the HDL file and draw the diagram of the gates.
Although it cannot import HDL files, Logisim is a great visual logic simulator. It's fairly quick to wire up a circuit given its HDL.
