New ContributorHi 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
New ContributorHi,
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?

Super ContributorUnfortunately, the LPM_CONSTANT IP is only supported in Cyclone IV GX, MAX V, MAX 10, Cyclone V, MAX II, Cyclone IV E devices.
Optionally, you could use the altsyncram Megafunction (e.g. RAM 1-port) with the Allow In-System Memory Content Editor to capture and update content independently of the system clock option.
The option will specifies whether to allow In-System Memory Content Editor in order to capture and update content independently of the system clock. This option is not applicable for MLAB and LCs memory block type.
Best Regards,
