2.2.1 Programming Bitstream
The programming bitstream contains programming data for FPGA fabric and/or eNVM (partial or full
content). Programming bitstream is always encrypted with the default key.
For additional security, custom security keys can be set in the security policy manager (SPM). For more
information, see the SPM section in the Libero SoC User Guide. If custom security is used default key
will be disabled.
The following table lists the bitstream size. Size does not change with device utilization. For information
about devices offering with and without transceivers and data security (T, TS, S), see the SmartFusion2
Product Brief and IGLOO2 Product Brief.

Post-Compile PDC file
- Post-Compile I/O PDC file generated
automatically if you explicitly add/modify your
I/O constraints after compilation
Post-Compile I/O Editor
- Assign pins and attributes
- Check rules
- State Management on Modifications
Pre-Compile Constraint Editor
- I/O constraint and Floorplan constraint
files are separated
- Enables you to import timing constraint (SDC)
files before compilation
