ECE 4110– Sequential Logic Design

1. ECE 4110– Sequential Logic Design Lecture #2 • Agenda • Logic Design Tools • Announcements • n/a

2. Logic Design Tools • MS Visio- a generic drawing program.- industry is converging on this program for documentation.- has built in shape libraries, including analog/digital logic.- we’ll use it for this class to create clean schematics.

3. Logic Design Tools • MS Visio Predefined Shapes

4. Logic Design Tools • ModelSim (by Mentor Graphics)- an HDL Simulation (VHDL and Verilog)- widely used in industry- has color-coded text editing for keywords- has console for verification reporting- we’ll use for homework & before FPGA synthesis.

5. Logic Design Tools • ModelSim Simulation Waveform ProjectNavigator Console

6. Logic Design Tools • ModelSim Text Editor

7. Logic Design Tools • Xilinx ISE - Integrated Software Environment (ISE)- Implementation tool - compile / simulate- synthesis- technology mapping- place and route- back annotation for post-route simulation and timing verification- can do similar simulation as in ModelSim- this is where we : - select FPGA to target - assign signal pins - set timing constraints - set placement constraints - set routing constraints - generate programming file - download file to FPGA, EEprom, or CPLD using the JTAG interface.
