simulate c program from nios in modelsim 10.1

[Altera_Forum]

Hi everybody! 

 This morning I have found this problem when I run my c program in Eclipse with Nios II modelsim configuration.  This error message appears:  Problem ocurred:  Failed Executing: C:/altera/10.1/quartus\bin\perl\bin\perl.exe C:/altera/10.1/quartus\sopc_builder/bin/run_modelsim.pl C:\altera\10.1\modelsim_ase\win32aloem,C:/Users/ifdm/workspace/quartus/ifdm_project,mvbc_system return code: 127  Can anybody help?  Thank you very much.

ok I think I have fixed the problem runing from the console: 

 perl c:/altera/10.1/quartus/sopc_builder/bin/run_modelsim.pl c:/altera/10.1/modelsim_ase/win32aloem,c:/Users/ifdm/workspace/quartus/ifdm_project,mvbc_system  But my problem now is that in the simulation I don`t see any changes in the instruction buses of the cpu.  Neither see any data in the jtag_uart_log.  The ram is initalized with the code of the program with elf2hex, elf2dat and nios2_elf_nm because I have introduced this line  NIOS2_BSP_ARGS="--default_sections_mapping sdram"  in create-this-bsp file.   My simulation lasts 1 ms, 1000 us , maybe is a short time. I am thinking of using these simulation options: small c library and reduced device drivers.   Any idea in how to take less time in simulation and how to fix the problem no-instruction-interaction with the cpu in the program simulation?

Hi, I'm getting the same error message too. How do you run it from the console window? I mean where do you type the text with the '\' changed into '/'? 

 My error message is:  Failed Executing: C:/altera/10.1/quartus\bin\perl\bin\perl.exe C:/altera/10.1/quartus\sopc_builder/bin/run_modelsim.pl C:\altera\10.1\modelsim_ase\win32aloem,C:/altera_trn/NiosII_HW/NiosII_1Day/NiosII_CIII_3C25/niosII_lab,niosII return code: 127    --- Quote Start ---  ok I think I have fixed the problem runing from the console:  perl c:/altera/10.1/quartus/sopc_builder/bin/run_modelsim.pl c:/altera/10.1/modelsim_ase/win32aloem,c:/Users/ifdm/workspace/quartus/ifdm_project,mvbc_system    --- Quote End ---

Hi I have the same problem; 

I resolved opening modelsim directly from the SOPC Builder and then typing "s" and "w" into the transcript modelsim window. for more: http://cseweb.ucsd.edu/~tweng/cse143/nii_sopcbuilder_1day_labguide.pdf page 69.  ale.
