5.4.2.1. Creating Memory Initialization Files
The mem_init.mk file includes targets designed to help you create memory initialization files (.dat, .hex, .sym, and .flash). The mem_init.mk file is designed to be included in your application makefile. Memory initialization files are used for HDL simulation, for Quartus Prime compilation of initializable FPGA on-chip memories, and for flash programming. Memories that can be initialized include M512 and M4K, but not MRAM.
Although the application makefile provides the mem_init.mk targets, it does not build any of them by default. The SBT creates the memory initialization files in the application directory (under a directory named mem_init). The SBT optionally copies them to your Quartus Prime project directory and HDL simulation directory.
QUARTUS_PROJECT_DIR = ../my_hw_design MEM_INIT_FILE := $(BSP_ROOT_DIR)/mem_init.mk include $(MEM_INIT_FILE)
Target | Operation |
---|---|
mem_init_install | Generates memory initialization files in the application mem_init directory. If the QUARTUS_PROJECT_DIR variable is defined, mem_init.mk copies memory initialization files to your Intel® Quartus® Prime project directory named $(QUARTUS_PROJECT_DIR). |
mem_init_generate | Generates all memory initialization files in the application mem_init directory. This target also generates a Quartus Prime IP File (.qip). The .qip file tells the Quartus Prime software where to find the initialization files. |
mem_init_clean | Removes the memory initialization files from the application mem_init directory. |
.hex | Generates all .hex files. |
.dat | Generates all .dat files. |
.sym | Generates all .sym files. |
.flash | Generates all .flash files. |
<memory name> | Generates all memory initialization files for <memory name> component. |
