This directory contains the the 5.8 version of Library Exchange Format (LEF) and Design
Exchange Format (DEF). LEF and DEF are distributed free of charge. See the
License.txt file in the LEF and DEF modules for conditions attached to the use of this
software, and the copying or distribution of it.
The Make programs for some systems may not be able to process the Makefile for the
LEF/DEF utilities. If your system’s native Make program returns errors when building
LEF/DEF, use GNU Make, or change the Makefiles so that they work on your system.
Mixing 5.4, 5.5, 5.6 and 5.7 Syntax with 5.8 Syntax
Use caution when mixing versions 5.4, 5.5, 5.6, and 5.7 syntax in LEF and DEF files. If you
include obsolete 5.4, 5.5, 5.6 and 5.7 constructs in a 5.8 file, the reader generates a warning.
Documentation
Documentation for the LEF and DEF application programming interfaces can be found in
the lef/doc and def/doc subdirectories, but it has not yet been updated with the
changes required for the new 5.8 syntax. Please contact Cadence for the version of
the LEF/DEF 5.8 syntax.
Bug Reporting
Please report issues with this version of the LEF/DEF 5.8 parser directly to Cadence.
Email mguiney@cadence.com
Platforms Supported
The LEF/DEF utilities have been tested on Linux RH 5.5. They should also work on Solaris 5.10.
Installation
The following information explains how to compile the LEF and DEF packages.
Installing LEF
To install LEF, do the following:
Change directories (cd) to the lef subdirectory containing the package’s source code.
To compile and build the package, type the following command:
gmake
To set DEBUG with OPTIMIZE_FLAG, type the following command:
gmake release
To install headers before compiling lefrw lefdiff lefwrite, type the following
command:
gmake installhdrs
Optionally, to run the tests that come with the package, type the following command:
./gmake test
NOTE: To remove the program binaries and object files from the source code directory,
type the following command:
gmake clean
Installing DEF
To install DEF, do the following:
Change directories (cd) to the def subdirectory containing the package’s source code.
To compile and build the package, type the following command:
gmake
To set DEBUG with OPTIMIZE_FLAG, type the following command:
gmake release
To install headers before compiling defrw defdiff defwrite, type the following command:
gmake installhdrs
Optionally, to run the tests that come with the package, type the following command:
