7.10. Decoder Parameters

The following table lists the ALTECC decoder IP core parameters.

Table 27.  ALTECC Decoder Parameters
Parameter Name Type Required Description
WIDTH_DATAWORD Integer Yes Specifies the width of the raw data. Values are 2 to 64. The default value is 8.
WIDTH_CODEWORD Integer Yes Specifies the width of the corresponding code word. Values are 6 to 72, excluding 9, 17, 33, and 65. If omitted, the default value is 13.
LPM_PIPELINE Integer No Specifies the register of the circuit. Values are from 0 to 2. If the value is 0, no register is implemented. If the value is 1, the output is registered. If the value is 2, both the input and the output are registered. If the value is greater than 2, additional registers are implemented at the output for the additional latencies. If omitted, the default value is 0.
Create a 'syn_e' port Integer No Turn on this parameter to create a syn_e port.
