G–2 Appendix G: Conversion from v2.2.x
Receiver Signals
POS-PHY Level 4 IP Core User Guide December 2014 Altera Corporation
Table G–1 shows the new v2.4.x and 2.3.x receiver signal names as they exist in the
top-level file, their equivalent v2.2.x signal names (if applicable), and notes explaining
the changes.
Table G–1. Receiver Signal Changes (Part 1 of 3)
Version 2.4.x and 2.3.x Signal
Name
Version 2.2.x Signal Name Notes
rdclk rdclk
No change.
rctl rctl
rdat[15:0] rdat[15:0]
rsclk rsclk
rstat[1:0] rstat[1:0]
rdint_clk rrefclk
Clock derived from
rdclk
. Signals infixed by
_rd_
are synchronous to this domain.
rdint_reset_n –
New. Tied high in the IP Toolbench top-level file.
Refer to “Clock Structure” on page 4–9 for
usage.
rxsys_clk a0_arxclk
System clock. Signals infixed by
_ry_
are
synchronous to this clock. Refer to “Clock
Structure” on page 4–9 for usage.
rxsys_reset_n –
New. Tied high in the IP Toolbench top-level file.
Refer to “Clock Structure” on page 4–9 for
usage.
rxreset_n rxreset_n
No change. Resets all domains.
rxinfo_aot[12:0] rxinfo_aot[15:0]
Change in port width.

err_aN_fifo_parityN –
New.
stat_aN_fifo_emptyN stat_a0_rxfifo_empty
No change.
err_ry_fifo_oflwN err_xx_rxfifo_oflw
In version 2.2.x, this signal is in the
rrefclk
domain; in version 2.3.0, this signal is in the
rxsys_clk
domain.
ctl_ry_errchk_chkpkt ctl_xx_errchk_chpkt
No change.
