Parameter Settings
The IPexpress? tool is used to create IP and architectural modules in the Diamond or ispLEVER software. Refer to
“IP Core Generation” on page 22 for a description on how to generate the IP.
Table 3-1 provides the list of user configurable parameters for the Block Viterbi Decoder IP core. The parameter
settings are specified using the Block Viterbi Decoder IP core Configuration GUI in IPexpress. The numerous PCI
Express parameter options are partitioned across multiple GUI tabs as shown in this chapter.
