Abstract (en)
This paper presents the software implementation of an adjustable PWM (Pulse Width Modulator) prototype, developed in Verilog code, which functions as a training tool at the undergraduate level, or for the development of small projects. At the schematic level, the prototype presents the main module called PWM which integrates three modules (frequency, useful cycle, and display), as a complement to carry out results under the conditions specified in the functional profile. The base module integrates combinational and sequential circuits, i.e. counters, comparators, flip flops, function generators, etc. The final results obtained by simulation show the expected behavior in terms of frequency setting, duty cycle, and display.

Este artículo presenta la implementación, en cuanto a software, de un prototipo de PWM (Modulador por Ancho de Pulso) ajustable, desarrollado en código Verilog, que funcione como herramienta de formación en el ámbito de pregrado, o el desarrollo de pequeños proyectos. En cuanto a esquema, el prototipo presenta un módulo principal llamado PWM el cual integra tres módulos (frecuencia, ciclo útil y display), como complemento para llevar a cabo resultados bajo las condiciones especificadas en el perfil funcional. La base de los módulos integra circuitos combinacionales y secuenciales, es decir contadores, comparadores, Flip Flops, generadores de funciones, etc. Los resultados finales obtenidos por simulación muestran el comportamiento esperado en cuanto a ajuste de frecuencia, ciclo útil y visualización.
