Hi, when i'm trying to start compilation, i get this message: Error (10528): VHDL error at spwstream.vhd(294): value "0" is outside the target constraint range (1 to 255) Error (10346): VHDL error at spwstream.vhd(292): formal port or parameter "disconnect_time" must have actual or default value

292 recv_inst: spwrecv 293 generic map( 294 disconnect_time => disconnect_time, 295 rxchunk => rxchunk )

What i'm doing wrong?

My stupid... close this question

Perhaps system clock frequency was set to zero. Closing report. :-)
