Estoy trabajando en un proyecto Verilog usando un FPGA (BEMICROMAX10) y algunos componentes de la placa base. El proyecto consiste en hacer un reloj digital en el que también puede configurar la hora utilizando los botones del FPGA. Me doy cuenta de que este código verilog no es la forma más eficiente de escribir esto, pero es la forma en que lo tengo configurado actualmente y la fecha límite se acerca, por lo que no se puede reiniciar. Creo que casi he terminado, así que espero que ustedes puedan superar el último obstáculo.
El tiempo de segundos a minutos a horas, funciona perfectamente cuando lo enciendo pero no puedo hacer que los botones funcionen para cambiar los minutos y las horas manualmente (mientras que los segundos se están ejecutando). Si nos fijamos en la línea 98 después de la gran cantidad de segundos, me encuentro con el error cuando agrego 'o posedge outm'. He intentado otras cosas, pero parece que recibo el error 'no puedo coincidir con los operandos' o el error 'múltiples controladores constantes' que asumo que me dice que estoy tratando de cambiar countmin y counthr con múltiples entradas (de clk y btn ). Estoy realmente atascado y no tengo idea de a dónde ir desde aquí.
Acabo de hacer una edición para conducir slow_clk2 con otra entrada de reloj en el FPGA, y agregué la línea de salida para el botón, pero aún no tengo suerte.
Gracias por tu ayuda.
