Hi everybody, I've created a function block with *Input:CLK and IO with 7 bits (CLK for clock and IO for defination 7 SW in FPGA Spartan 3:from SW0 to SW6) *Output:PMW1,PWM2,PWM3 And then i definate Floorplan IO and run Synthesize but have enrrors ERROR:ConstraintSystem:59 - Constraint <NET "PWM1" LOC = "N7" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> ERROR:ConstraintSystem:59 - Constraint <NET "PWM2" LOC = "T8" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> ERROR:ConstraintSystem:59 - Constraint <NET "PWM3" LOC = "R6" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> ERROR:ConstraintSystem:59 - Constraint <NET "SchalterIO<0>" LOC = "F12" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> ERROR:ConstraintSystem:59 - Constraint <NET "SchalterIO<1>" LOC = "G12" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> ERROR:ConstraintSystem:59 - Constraint <NET "SchalterIO<2>" LOC = "H14" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> ERROR:ConstraintSystem:59 - Constraint <NET "SchalterIO<3>" LOC = "H13" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> ERROR:ConstraintSystem:59 - Constraint <NET "SchalterIO<4>" LOC = "J14" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> ERROR:ConstraintSystem:59 - Constraint <NET "SchalterIO<5>" LOC = "J13" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> ERROR:ConstraintSystem:59 - Constraint <NET "SchalterIO<6>" LOC = "K14" |> ERROR:ConstraintSystem:59 - Constraint <IOSTANDARD = LVCMOS33 ;> Please help me Thanks you.
Beside exist too errors after i run file pwm_sc.ucf "ERROR: the file pwm_sc.ngd is missing, the Constraints Editor can not be launched." How can i fix these error? Thanks you again

please post the entity of your design and the constrains

Maybe it's easier for you to discuss this in german? http://www.mikrocontroller.net/forum/fpga-vhdl-cpld The errors are saying mainly that these signals were not found. Could be they were optimized away, since the compiler considered they as not used. This can by an error in the description or maybe since your design is not complete yet.
