Honored Contributorthanks Tricky, but I have the same LATCH problems with the rest of signals,
Warning (10631): VHDL Process Statement warning at Ledsv2.vhd(57): inferring latch(es) for signal or variable "nReset", which holds its previous value in one or more paths through the process Warning (10631): VHDL Process Statement warning at Ledsv2.vhd(57): inferring latch(es) for signal or variable "leds_r", which holds its previous value in one or more paths through the process Warning (10631): VHDL Process Statement warning at Ledsv2.vhd(57): inferring latch(es) for signal or variable "LEDR", which holds its previous value in one or more paths through the process Warning (10631): VHDL Process Statement warning at Ledsv2.vhd(57): inferring latch(es) for signal or variable "stat_act", which holds its previous value in one or more paths through the process Warning: LATCH primitive "stat_act" is permanently disabled Warning: LATCH primitive "leds_r[1]" is permanently disabled this exists from leds_r(0) to leds_r(17) Warning: LATCH primitive "LEDR[0]$latch" is permanently disabled Warning: Output pins are stuck at VCC or GND Warning (13410): Pin "LEDR[0]" is stuck at GND Warning (13410): Pin "LEDR[1]" is stuck at GND Warning (13410): Pin "LEDR[2]" is stuck at GND Warning (13410): Pin "LEDR[3]" is stuck at GND Warning (13410): Pin "LEDR[4]" is stuck at GND Warning (13410): Pin "LEDR[5]" is stuck at GND Warning (13410): Pin "LEDR[6]" is stuck at GND Warning (13410): Pin "LEDR[7]" is stuck at GND Warning (13410): Pin "LEDR[8]" is stuck at GND Warning (13410): Pin "LEDR[9]" is stuck at GND Warning (13410): Pin "LEDR[10]" is stuck at GND Warning (13410): Pin "LEDR[11]" is stuck at GND Warning (13410): Pin "LEDR[12]" is stuck at GND Warning (13410): Pin "LEDR[13]" is stuck at GND Warning (13410): Pin "LEDR[14]" is stuck at GND Warning (13410): Pin "LEDR[15]" is stuck at GND Warning (13410): Pin "LEDR[16]" is stuck at GND Warning (13410): Pin "LEDR[17]" is stuck at GND I think I don't understand how the latch works. I have a similiar code from a friend that works on a DE2-70, and there is no reference to any latch. What I'm missing? Thanks Guillermo
