Xilinx Development System
5
Xilinx Processor Cores

• Power PC
• Built in hard core structure within the FPGA
• MicroBlaze
• RISC soft core
• Intellectual Property (IP) to support Xilinx FPGA
  is available

6
Xilinx Development System
7
Gajski Diagram

• Design Method
• Work from one level of abstraction to the next
• Start from the outside and work in

8
Gajski Y Diagram

• Algorithm mine system design
• Processor FPGA in XUP board
• Chip floor plan Power PC, memory on and off
  chip
• Remainder of steps are covered with
  comprehensive tools available for the Xilinx FPGA

Embedded Development Kit (EDK)

• Xilinx tool kit for use with
• PowerPC
• Microblaze

12
Xilinx Integrated Software Environment (ISE)

• Puts source file in one place
• System Generator a high level of abstraction
• Embedded development kit allows one to set up a
  system
• Xilinx System Generator uses SIMULINK

13
Xilinx Integrated Software Environment (ISE)
ISE
14
Simulink

• Allows one to simulate signals and systems
• Behavioral Level
• It does not know anything about the Xilinx FPGA
• Must give it the Xilinx block

15
ModelSim XE III

• Simulation at the Physical Layer
• Debugging
