GTPE2_CHANNEL Attributes
The GTPE2_CHANNEL primitive has attributes intended only for simulation. Table 1-3 lists the
simulation-only attributes of the GTPE2_CHANNEL primitive. The names of these attributes start
with SIM_.
Table 1-3: GTPE2_CHANNEL Simulation-Only Attributes
Attribute Type Description
SIM_RESET_SPEEDUP String
If the SIM_RESET_SPEEDUP attribute is
set to TRUE (default), an approximated reset
sequence is used to speed up the reset time
for simulations, where faster reset times and
faster simulation times are desirable. If the
SIM_RESET_SPEEDUP attribute is set to
FALSE, the model emulates hardware reset
behavior in detail.
SIM_RECEIVER_DETECT_PASS String
SIM_RECEIVER_DETECT_PASS is a
string TRUE/FALSE attribute to determine if
a receiver detect operation should indicate a
pass or fail in simulation.
SIM_TX_EIDLE_DRIVE_LEVEL String
SIM_TX_EIDLE_DRIVE_LEVEL can be
set to 0, 1, X, or Z to allow for simulation of
electrical idle and receiver detect operations
using an external pull-up resistor. The default
for this attribute is X.
SIM_VERSION String
This attribute selects the simulation version
to match different steppings of silicon. The
default for this attribute is 1.0.
