Figure 1–18. 8B/10B Conversion Format
The ALTGX MegaWizard Plug-In Manager provides the tx_ctrlenable port to
indicate whether the 8-bit data at the tx_datain port should be encoded as a control
word (Kx.y). When tx_ctrlenable is low, the 8B/10B encoder block encodes the byte
at the tx_datain port (the user-input port) as data (Dx.y). When tx_ctrlenable is
high, the 8B/10B encoder encodes the input data as a Kx.y code group. The waveform
in
the tx_datain bytes are encoded as a data word (Dx.y).
The IEEE 802.3 8B/10B encoder specification identifies only a set of 8-bit characters
for which tx_ctrlenable should be asserted. If you assert tx_ctrlenable for any
other set of bytes, the 8B/10B encoder might encode the output 10-bit code as an
invalid code (it does not map to a valid Dx.y or Kx.y code), or unintended valid Dx.y
code, depending on the value entered. It is possible for a downstream 8B/10B decoder
to decode an invalid control word into a valid Dx.y code without asserting code error
flags.
