Module 1: Introduction and Setup
1-1 Introduction
The Clock Concurrent Optimization (CCOpt) Rapid Adoption Kit (RAK) introduces you
to running native CCOpt in EDI System. It shows the basics on how to configure and run
native CCOpt plus tools and commands to analyze and debug the results. It assumes you
are familiar with running EDI System.
1-2 Leon Design Information
The design in this lab is a Leon processor. The Leon design is a block level design with
35K instances, 4 memories, and 1500 IO pins. The library used is a Cadence Generic
45nm library using 9 routing layers.
There are three main clocks in this design (test_clk, my_clk and div_clk) as defined by the
following SDCs:
create_clock -name {test_clk} -period 8.000 \
-waveform { 0.000 4.000 } [list [get_ports {scan_clk}]]
create_clock -name {my_clk} -period 4.000 \
-waveform { 0.000 2.000 } [list [get_ports {clk}]]
create_generated_clock -name div_clk -source \
[get_ports {clk}] -divide_by 2 [get_pins {clk_div_reg/Q}]
A schematic of the clock structure is below:

1-3 Setting up EDI System and the Lab Directory
1. Download and install the EDI System 13.2 software from
http://downloads.cadence.com.
2. Extract the RAK database and change directory to the work directory:
linux% tar xfz RAK_13.2_CCOpt.tgz
linux% cd RAK_13.2_ccoCCOpt
3. Verify the encounter executable is in your path by typing:
linux% which encounter
4. Start EDI System:
linux% encounter
5. Load in the starting design by running the following in the EDI System console:
source DATA/prects.enc
