Receiver Testbench Examples
To simulate errors using these tasks, you must turn on dynamic phase alignment
(DPA) and Atlantic error checking when parameterizing your MegaCore function.

Task Format
General Description
Input Parameters Description
port[7:0] sets the port address (ADR bits [11:4] of SOP
control word).
err sets the error code for inserting various protocol
errors into the SPI-4 stream. The error codes are:
0 = no error
1 = invert DIP4 and set error bit
2 = omit start of packet (SOP)
3 = omit end of packet (EOP)
4 = insert a payload control word mid-packet (not really
an error)
Sends a single packet
5 = insert an idle followed by a payload control word
spi_gen.pkt2
and can optionally
mid-packet (not really an error)
(port,err,size,pkt_num)
insert various
protocol errors.
6 = set SOP in idle EOP (odd or even) control word
following packet
7 = set SOP in idle EOP (abort) control word following
packet
8 = set EOP (abort) for packet and insert error bit in
header
9 = invert dip4 but do not set error bit
All other values are undefined.
size sets the length field of the packet header.
pkt_num[7:0] sets the value of the first byte after the
header. This byte is then incremented for the rest of the
packet.
Sends a control word
for one clock cycle.
spi_gen.cw
(word[15:0],dip4err)
POS-PHY Level 4 MegaCore Function User Guide
The DIP4 is auto
calculated and
inserted into word
[3:0]. The DIP4
calculation can be
inverted.
word[15:0] is the control word to be inserted.
When the dip4err bit is set, the DIP4 calculation is
inverted.
