2.1.3.1 RTL Inference during Synthesis

Synplify Pro ME can infer an LSRAM from RTL automatically based on memory logic used in the design. In this case, synthesis handles all the signal connections of the LSRAM block to the rest of the design and sets the correct values for the static signals needed to configure the appropriate operational mode. The tool ties unused dynamic input signals to ground and provides default values to unused static signals. If a design requires more memory blocks than the blocks available in the device, the Synthesis tool will infer fabric registers for the extra memory blocks.
