Constants in In-System Memory Content editor

Hi, Can someone please help me in defining constants to modify using In-System Memory Content editor? I am using Quartus Prime Pro 19.2 version. Regards, Pavan

Hi Richard,

I already have the working scripts to read and write data in memory.

I want to know if there is a possibility to read and modify a constant value (not in memory).

I have read somewhere that Quartus implements constants in registers rather than LUTs when need to be modified using ISMCE.

I want to know how to do this.

Regards,

Pavan

Hi,

I believe that a way to define constants that can be modified using ISMCE in the earlier quartus versions was through LPM_CONSTANT IP.

In quartus 19.4/19.2 versions, I do not see this IP.

Is there an alternative to this?
