Chapter 5: Testbench
Testbench Components Description
If the iptg task is called, idle cycles are inserted between write operations. The
probability of idles between write cycles decreases with larger values of prob .
Table 5–3. iptg Task Field Description
5–11
Field Location
in Task
Field
Valid Values
Description
The prob field sets the probability of a transaction gap. The
1
prob
0 to 0xFFFF_FFFF
(integer)
probability decreases with a larger value of prob .
Before each transaction, a random number between 0 and
prob is generated and compared to prob/2 . If they match,
a random gap is inserted; if not, no gap is inserted.
2
min
0 to 0xFFFF_FFFF
(cycles)
The min field sets the minimum value, in Atlantic clock
cycles, for a random gap between AGEN write transactions.
The max field sets the maximum value, in Atlantic clock
3
max
0 to 0xFFFF_FFFF
(cycles)
cycles, for a random gap between AGEN write transactions.
A max field greater than or equal to the min field is required.
When max==min , no gap occurs.
– verbose(bit_value)
The verbose task enables or disables the display of AGEN verbose messages.
Table 5–4. verbose Task Field Description
Field Location
in Task
Field
Valid Values
Description
Setting bit_value to 1, enables the display of verbose
1
bit_value
1'b0 or 1'b1
messages.
Setting bit_value to 0, disables the display of verbose
messages (default).
– corrupt_sop
The corrupt_sop task corrupts the start of packet (SOP) of the next packet. When
called, it waits for the SOP and corrupts it (makes SOP==0). All the subsequent
packets are not corrupted.
– corrupt_eop
The corrupt_eop task corrupts the end of packet (EOP) of the next packet. When
called, it waits for the EOP and corrupts it (makes EOP==0). All the subsequent
packets are not corrupted.
AGEN Parameters
The MegaWizard Plug-In Manager sets these parameters based on the selected
configuration, and the parameters are fixed for a given SerialLite II configuration.
