Pin_mon Tasks - Verilog HDL
Table 5–11 shows the function of the pin_mon tasks.

Task

verbose_on
verbose_off
set_expect (bit_value)
Function
This task enables monitoring (the en input pin must also be set high to enable
monitoring).
This task disables monitoring (regardless of the value of the en input pin).
This task enables the display of verbose messages.
This task disables the display of verbose messages.
This task sets the expected pin value.
Clock and Reset Generator
The DUT and the SISTER use a common clock, with the frequency set by the
MegaWizard Plug-In Manager.
There is one master reset signal ( reset_n ) that resets all the logic in the demonstration
testbench (DUT, SISTER(s), AGENs, AMONs and status monitors).

Ensure reset_n to the MegaCore function starts high at Time=0 , and then goes low for
proper reset of the simulation model. Some simulators do not detect the transition if
reset_n is asserted low at T=0 .
To allow for easy modification, the reset section of the testbench is marked by
start–end comment tags:
SERIALLITE2_TB_RESET_START
SERIALLITE2_TB_RESET_END
The clock and reset utilities are included in the testbench top-level file.
Custom PHY IP Core
The DUT and the SISTER use an external transceiver for Arria V and Stratix V
configurations. You are required to separately instantiate the Custom PHY IP core
using the MegaWizard Plug-In Manager.
Example Testbench – Verilog HDL
To allow for easy modification of the demonstration testbench, its main section is
marked by start–end tags:
//SERIALLITE2_TB_MAIN_START
//SERIALLITE2_TB_MAIN_END
Because there is no Atlantic to Atlantic score-boarding, the demonstration testbench
focuses on passing error-free data rather than errored data. Any error condition that
involves dropped or errored packets, must be handled in the testbench by setting
proper expectations.
