hi: guys
i use the quartus 7.2 web edition and modelsim altera6.1g to simulate next program library IEEE; use IEEE.std_logic_1164.all; use IEEE.std_logic_unsigned.all; entity fpdiv is port ( DIVz: out STD_LOGIC; A: in STD_LOGIC_VECTOR (7 downto 0):="11111111"; B: in STD_LOGIC_VECTOR (7 downto 0):="00000010"; data_out: out STD_LOGIC_VECTOR (7 downto 0) ); end fpdiv; architecture fpdiv_arch of fpdiv is signal REMAINDERS0 : STD_LOGIC_VECTOR (5 downto 0); signal REMAINDERS1 : STD_LOGIC_VECTOR (5 downto 0); signal REMAINDERS2 : STD_LOGIC_VECTOR (5 downto 0); signal REMAINDERS3 : STD_LOGIC_VECTOR (5 downto 0); signal DIVISORS0 : STD_LOGIC_VECTOR (5 downto 0); signal DIVISORS1 : STD_LOGIC_VECTOR (5 downto 0); signal DIVISORS2 : STD_LOGIC_VECTOR (5 downto 0); signal DIVISORS3 : STD_LOGIC_VECTOR (5 downto 0); signal Q_TEMP : STD_LOGIC_VECTOR (7 downto 0); signal Z0 : STD_LOGIC_VECTOR (2 downto 0); signal Z1 : STD_LOGIC_VECTOR (2 downto 0); signal ZERO : STD_LOGIC; begin Z0 <= (others => '0'); Z1 <= (others => '0'); DIVISORS0 <= Z0 & B(2 downto 0); REMAINDERS3 <= Z1 & A(2 downto 0); DIVISORS1 <= DIVISORS0(4 downto 0) & '0'; DIVISORS2 <= DIVISORS1(4 downto 0) & '0'; DIVISORS3 <= DIVISORS2(4 downto 0) & '0'; Q_TEMP(0) <= '1' when (REMAINDERS1 >= DIVISORS0) else '0'; Q_TEMP(1) <= '1' when (REMAINDERS2 >= DIVISORS1) else '0'; Q_TEMP(2) <= '1' when (REMAINDERS3 >= DIVISORS2) else '0'; Q_TEMP(3) <= '1' when (REMAINDERS1 >= DIVISORS0) else '0'; Q_TEMP(4) <= '1' when (REMAINDERS2 >= DIVISORS1) else '0'; Q_TEMP(5) <= '1' when (REMAINDERS3 >= DIVISORS2) else '0'; Q_TEMP(6) <= '1' when (REMAINDERS2 >= DIVISORS1) else '0'; Q_TEMP(7) <= A(7) xor B(7); REMAINDERS2 <= REMAINDERS3 - DIVISORS2 when Q_TEMP(2) = '1' else REMAINDERS3; REMAINDERS1 <= REMAINDERS2 - DIVISORS1 when Q_TEMP(1) = '1' else REMAINDERS2; REMAINDERS0 <= REMAINDERS1 - DIVISORS0 when Q_TEMP(0) = '1' else REMAINDERS1; ZERO <= '1' when B(6 downto 0) = Z1 else '0'; DIVz <= '1' when ZERO = '1' else '0'; data_out <= (others => '0') when ZERO = '1' else Q_TEMP; end fpdiv_arch; the compile is success , when i use modelsim-altera to run EDA RTL simualtion i get next problem. Info: Quartus(args): --rtl_sim fpdiv fpdiv Info: Start Nativelink Simulation process Info: NativeLink has detected VHDL design -- VHDL simulation models will be used Info: Starting NativeLink simulation with ModelSim-Altera software Error: Can't launch the ModelSim-Altera software -- the path to the location of the executables for the ModelSim-Altera software were not specified or the executables were not found at specified path. Error: You can specify the path in the EDA Tool Options page of the Options dialog box or using the Tcl command set_user_option. Error: NativeLink simulation flow was NOT successful Info: For messages from NativeLink scripts, check the file C:/altera/72/quartus/fpdiv_nativelink_simulation.rpt i already installation modelsim-altera and run is ok. i set the setting in quartus 7.2 is following,the test bench is generation from quartus testbench name: fpdiv.vht top level model in test bench : fpdiv_vhd_tst design instance name in test bench :TB i set the path in environment variance point to the modelsim-altera why i have this problem please tell me , i am a new coming. thanks連結已複製

Goto Tools->Options. Under EDA Tools Option (General), set your modelsim-altera path (e.g. C:\altera\72\modelsim_ae\win32aloem). Hope it helps.
please
modelsim v 6.1 is installed but not started when i double click on its icon quartus 7.2 running is ok but i need to work with modelsim(6.1)and quartus (7.2) together and i have window xp also i download a licesing shared the both, i tree the following approch but it was not ok. - Right click on My Computer icon, click properties - Select Advanced tab and click on the Environment Variables button (right above OK button) - in the "User Variables for user_name" section, click new - Type in LM_LICENSE_FILE in the Variable Name section - Type in the path (where your license file is located, e.g., c:\altera\license.dat) in the Variable Value section - Click OK - Close all the remaining windows by clicking OK in each of them please help me
