Automatic Placement and Routing using Synopsys IC Compiler CS250 Tutorial 6 (Version 100609a) October 6, 2009 Yunsup Lee This is an early version of tutorial 6 which is not done yet. In this tutorial you will gain experience using Synopsys IC Compiler to probe your design. The following documentation is located in the course locker (~cs250/docs/manuals) and provides additional information about Design Compiler, Design Vision, the Design Ware libraries, and the Synopsys 90nm Standard Cell Library. • • • • • •

Getting started Before using the CS250 toolflow you must run the course setup script with the following command. % source ~cs250/tools/cs250.bashrc
Reporting the Total Area Run IC Compiler using the following commands. If you have already place and routed your design, you can skip the make command. % cd $TUT6_ROOT/build/icc-par/current-icc % make % icc_shell icc_shell> source icc_setup.tcl icc_shell> open_mw_lib $MW_DESIGN_LIBRARY icc_shell> open_mw_cel $ICC_CHIP_FINISH_CEL icc_shell> report_area -hierarchy
Highlighting the Hierarchy Run IC Compiler using the following commands.

% cd $TUT6_ROOT/build/icc-par/current-icc % icc_shell icc_shell> source icc_setup.tcl icc_shell> gui_start Then open your chip finish icc cell by following the steps. First, start with File > Open Design.
Open smipsCore LIB.

Select chip finish icc.
Choose Placement > Color by Hierarchy. Then hit Reload. Pick Color Specific hierarchical cells. Then select the button on the most right which is for Browse for cells. Pick your register file and ALU from the list.
Now you will get highlighted cells from your design.
