Logisim HDL language and Logisim • Most real-‐world hardware design is done using a text-‐ based hardware descrip:on language – VHDL, Verilog, etc. – Schema:cs can be compiled into a text decrip:on – Can use a simulator to test the circuit – Other back-‐end tools op:mize, perform layout and wire rou:ng, floorplan, etc. – Final spec is either downloaded onto a programmable device, or etched into silicon. – Interac:ve, graphical schema:c editor – Educa:onal use, user-‐friendly
• We will use Logisim for all hardware design
Verilog Example: Decoder
Other CAD tools in circuit design • Circuit level tool vendors – Cadence, Synopsys, etc. – other smaller players
• Board level tool vendors – Al:um, Eagle and many more
