Do all RAM-structures support In-system Memory Editor?

Do all types of RAM allow the use of In-System Memory Editor?

I a trying to debug a Dual-port RAM , generated by the Megawizard. When I get to the "Mem Int" tab, I am looking for "Allow In-System Memory Content Editor to capture & update content independently of the system clock".

I see it for RAM:1 PORT, but not for RAM :2 port - anyone know why?

The "In-System Modification of Memory and Constants" chapter(QII53012) says use altsyncram, (which can be configured as Dual-port), but that is not an option available via the Megawizard in QII 11 sp1. (Device family Cyclone-II).

Thanks.

    if you use "...independently of the system clock" the memory editor will be implemented as a second port of your memory.. if you already use 2 port, this will not be possible, because there is nor 3 port memory

    keep in mind, your describing hardware not using some c style array
