Value

Parameter

For master interfaces that do not use the waitrequest

signal. The read wait time indicates the number of

cycles before the master responds to a read. The timing

is as if the master asserted waitrequest for this

number of cycles.

N/A1Fixed read wait time (cycles)

For master interfaces that do not use the waitrequest

signal. The write wait time indicates the number of

cycles before the master accepts a write.

N/A0Fixed write wait time (cycles)

Specifies whether to turn on the register stage.On/OffOffRegistered waitrequest

Specifies whether to register incoming signals.On/OffOffRegistered Incoming Signals

Avalon-MM Monitor Assertion Checking API

Assertion checking uses the enable_waitrequest_timeout method to verify that waitrequest is asserted

for fewer cycles than the waitrequest timeout period. If the timeout period is violated, an error message

displays on the simulation console. Error flags are also displayed in the waveform viewer.

By default all assertions are enabled. However, depending on the parameterization of the Avalon-MM

interface, some assertions are automatically disabled. For example, you might have to turn off some assertion

checking to avoid the monitors generating error messages when injecting protocol errors. Protocol errors

are typically injected to test the Avalon-MM component’s error handling capability.

The names of all methods that enable assertions begin with set_enable_a. By default, if your testbench

includes the Avalon-MM monitor, the checking function is enabled. You can disable checking with the

DISABLE_ALTERA_AVALON_SIM_SVA macro.
