Quartus II Software Version 5.1 Critical Issue
Due to a recently discovered issue in Quartus® II software version 5.1, designs that use the encrypted intellectual property cores listed below may fail to compile in Quartus II software or fail functionally in simulation or hardware. The issue is caused by a failure to detect changes to encrypted IP core source files generated by SOPC Builder or IP Toolbench. Quartus II software versions 5.0 and earlier do not have this issue.
IP Cores Affected by This Critical Issue:
- Nios® II
- POS-PHY Level 4
- RapidIOTM
- SerialLite II
- SONET/SDH Compiler
How Can This Issue Affect My Design?
It has been identified that the Quartus II software version 5.1 does not properly detect changes to encrypted intellectual property cores including the Nios II embedded processor, POS-PHY Level 4, RapidIO, SerialLite II, and SONET/SDH Compiler cores. This detection failure can cause the Quartus II software compilation to fail during analysis and synthesis or result in hardware or simulation failures within the design logic after a successful compilation.
