Quartus compilation problem

Altera_Forum · ‎03-09-2010

Hi all,

I met a strange problem: when i use quartusii,a project first compiled need the Logic Elements is 13%,but then, i compiled again is 1%. :confused:

Hi cherry,

without any change ???? No design change, no settings changed ....

Kind regards

the program is when compilation of main program this error comes out

"Error (10482): VHDL error at up3_board1.vhd(34): object "txd_data" is used but not declared"..i already add the component program file UARTTransmitter.vhdl to this main program

any idea???

Hi,

I'm not a VHDL expert, but I think you have to define a signal called txd_data in your architecture.

Are you aware you have created a completly asynchronous design? there are no registers in this code.

Also, you have not instantiated a UART Transmitter.
