Question

Error (176310): Can't place multiple pins assigned to pin location Pin_D1 (IOPAD_X0_Y37_N7)
	Info (176311): Pin epcs_config_asd0_o is assigned to pin location Pin_D1 (IOPAD_X0_Y37_N7)
	Info (176311): Pin ~ALTERA_ASDO_DATA1~ is assigned to pin location Pin_D1 (IOPAD_X0_Y37_N7)

Answer

Use SOPC or Qsys and add “EPCS Serial Flash Controller”

error: can’t place multiple pins assigned to pin location

Question

Qsys: Warning: No matching role found

Answer

You may safely ignore these messages for Altera components because the signals are not required for design operation.

Question

Warning- "Properties (isMemoryDevice) have been set on interface uas - in composed mode these are ignored"

Answer

This warning means that the NIOS® II software tools may not see the isMemoryDevice assignment which will make it harder in the GUI to choose memory addresses at this range as being valid to store boot data
Warning- “Properties (isMemoryDevice) have been set on interface uas – in composed mode these are ignored”

Error (10558): VHDL error at dionysos_top.vhd(238): cannot associate formal port "bridge_cfi_flash_read_n" of mode "out" with an expression

Answer

Generate as Verilog, edit componen from std_logic_vector to std_logic!

Wrong Answer

Re-create Qsys tree. Updating from earlyer versions (ex. 12.1) to current version (13.1) is NOT safe!

You must have the 32-bit compatibility libraries installed for the Quartus II installer and software to operate properly.

Answer

Ubuntu apt-get install ia32 for 32-bit on 64-bit
Installing 32-bit libs on a 64-bit Linux system

$ sudo dpkg --add-architecture i386
$ sudo apt-get install lib32z1

Question

How to synthesis the whole project or just some VHDL files in the command-line?

Answer

Using Quartus from command line

Quartus-II Handbook Version 13.0, page 2-10 (or search ASSIGNMENT_FILES)
==> produces one example Makefile

$ quartus_map --help=makefiles

or

$ PATH=$PATH:/opt/altera/13.0/quartus/bin
$ quartus_map binary_ops_00000000 --source=binary_ops_00000000.v --family="Cyclone III" 
$ quartus_fit binary_ops_00000000
$ quartus_eda binary_ops_00000000 --formal_verification --tool=conformal
$ cp -v fv/conformal/binary_ops_00000000.vo output.v

:UnixTime  [ReturnVar]  [TimeStamp]
::
:: Computes the Unix time from the current local time as reported by the
:: operating system. The Unix time is the number of seconds that have elapsed
:: since midnight Coordinated Universal Time (UTC), January 1, 1970, not
:: counting leap seconds.
::
:: The result is returned in variable ReturnVar,
:: or the result is echoed if ReturnVar is not specified
::
:: If the TimeStamp is provided in the 2nd parameter, then the Unix time for
:: the TimeStamp is computed, rather then for the current time.
::
:: The TimeStamp must have the same format as used by WMIC:
::
::   YYYYMMDDhhmmss.ffffffSzzz
::
:: where:
::
::   YYYY   = gregorian year
::   MM     = month
::   DD     = day
::   hh     = hour in 24 hour format
::   mm     = minute
::   ss     = seconds
::   ffffff = fractional seconds (microseconds)
::   S      = timezone sign: + or -
::   zzz    = timezone: minutes difference from GMT
::
:: Each component must be zero prefixed as needed to maintain the proper width.
::
:: The ReturnVar parameter must be provided in order to use the TimeStamp.
:: A ReturnVar of "" will function the same as no ReturnVar. This enables the
:: specification of a TimeStamp without an actual ReturnVar.
