Description

ENABLE

RW

Setting this bit to 1 enables the Data Pattern Checker IP.

[16:8]

THROTTLE

RW

Specifies the throttle value which can be between 0–256, inclusively. Platform Designer uses this value in conjunction with a pseudo-random number generator to throttle the data generation rate.

Setting THROTTLE to 0 stops the Avalon® Data Pattern Checker IP. Setting it to 256 causes the Avalon® Data Pattern Checker IP to run at full throttle. Values between 0–256 result in a data rate proportional to the throttle value.

[17]

SOFT RESET

RW

When this bit is set to 1, all internal counters and statistics are reset. Write 0 to this bit to exit reset.

[31:18]

Reserved

If there is no exception, reading the exception_descriptor register bit register returns 0.
