Stratix IV GX - M9K and "three port Ram"

Hello.

I used Quartus II MegaWizard to make a "tri-port-ram" using M9K unit, in the width of 18X512.

(One Write Input, Two Read Inputs, Two Output Ports).

How can I verify that the module is based on a single m9k unit and not on two M9Ks?

    The easiest/fastest way without thinking too much about it is to simply create a blank project and set your MegaWizard file as the top level entity and compile it.

    Review the Fitter reports to see how many M9K it used.

    Thanks. Indeed, It can be seen that the Quartus uses two units of M9K to provide a "three-port" RAM unit with two Read-Inputs.

    Thank you very much.

    Lior.
