what is vsim command line?

 run_modelsim: $(test_info)
   $(MAKE) -C $(root_dir)/sim build_modelsim; \
   printf "" > $(test_results); \
   cd $(bld_dir); \
   vsim -c -do "run -all" +nowarn3691 \
   +test_info=$(test_info) \
   +test_results=$(test_results) \
   +imem_pattern=$(imem_pattern) \
   +dmem_pattern=$(dmem_pattern) \
   work.$(top_module) \
   $(MODELSIM_OPTS)

from this code I expect it to run modelsim in graphical mode. But I don’t understand what the test_results \ imem_pattern \ dmem_pattern parameters mean. Why are they transmitted to vsim if it does not have them?

let's go options by options:

-c

Command line mode This is why it is not starting in gui mode. remove that and it would do.

-do "run -all"

This what the simulator will do. "run -all" means that it will run util the simu stops by itself.

+nowarn3691

This is to remove a bunch a crazy modelsim warning as "# ** Warning: (vsim-3116) Problem reading symbols from linux-gate.so.1 : can not open ELF file."

+test_info=$(test_info) +test_results=$(test_results) +imem_pattern=$(imem_pattern) +dmem_pattern=$(dmem_pattern)

from the help: "Option accessible by PLI routine mc_scan_plusargs" This will be given to the PLI lib (weirdly the argument to enable the PLI is not present)

work.$(top_module)

This is the entity you are going to simulate as a top. (module: $(top_module) from lib work)

$(MODELSIM_OPTS)

given by your makefile, so we can't know from this code
