Read Data Out Characteristics

[stephenry]

Somewhat naive question, but my understanding of the read characteristics of the generated macros wasn't clear from the documentation. After a read has completed, and the data has become available at the output, if there is no subsequent operation (or the clock is gated), does the output remain valid indefinately?

[mguthaus]

No, it will only remain valid for that read cycle. At the next clock, it will become invalid no matter whether the operation is a write, read or noop.

[stephenry]

Does this apply too if the clock is gated once the data is available?

[mguthaus]

Yes, it does. The sense amps get shut off so the output will be invalid.
