| 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. |
