rxfreqlocked0
(1)
Input
When asserted indicates that the
pclk_in
used for PIPE
simulation is valid.
rxdataskip0
Output
For Gen3 operation. Allows the PCS to instruct the RX interface
to ignore the RX data interface for one clock cycle. The following
encodings are defined:
• 1’b0: RX data is invalid
• 1’b1: RX data is valid
eidleinfersel0[2:0]
Output
Electrical idle entry inference mechanism selection. The
following encodings are defined:
• 3'b0xx: Electrical Idle Inference not required in current
LTSSM state
• 3'b100: Absence of COM/SKP Ordered Set in the 128 us
window for Gen1 or Gen2
• 3'b101: Absence of TS1/TS2 Ordered Set in a 1280 UI interval
for Gen1 or Gen2
• 3'b110: Absence of Electrical Idle Exit in 2000 UI interval for
Gen1 and 16000 UI interval for Gen2
• 3'b111: Absence of Electrical idle exit in 128 us window for
Gen1
