Radiant 1.0 SP1

  • Re-compile with this service pack if users uses the LVDSE IO type in their design.
  • If CCU2 primitives are indicated in the Area Report of the LSE synthesis report file, there is a chance of getting an incorrect synthesis result from carry chain optimizations. It is advised to re-compile the design using this service pack to avoid a simulation and/or hardware operation failure. This fix is applicable for LSE only.
  • Fixed several other key customer defects resolving instability relating to map, place and route in the timing engine.

Radiant 1.0

  • Standardized Timing and Physical Constraints utilizing the popular SDC format to help you easily apply constraints to your designs.
