The following table lists the parameters for the ALTECC_DECODER megafunction.
Table 5-8: ALTECC_DECODER Megafunction 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.
Design Example 1: ALTECC_ENCODER
This design example uses the ECC encoder to encode an 8-bit wide input data to generate 13 bits of
output code word. This example uses the MegaWizard Plug-In Manager in the Quartus II software.
The following design files can be found in altecc_DesignExample1.zip:
• altecc_encode.qar (archived Quartus II design files)
• altecc_encode_ex_msim (ModelSim-Altera files)
Understanding the Simulation Results
The following settings are observed in this example:
• The data[] input width is set to 8 bits
• The output port, q[] has a width of 13 bits
• The clock enable (clocken) signal is enabled
• Pipelining is enabled, with an output latency of 2 clock cycles. Hence, the result is seen on the q[] port
two clock cycles after the input data is available
The following figure shows the expected simulation results in the ModelSim-Altera software.
