До этого не обращал внимания, но... где здесь указание на то, какая частота сигнала используется, куда вписать нестабильность частоты (квартус выдаёт критические ворненги относительно того, что нестабильность не задана). Возможно необходимо создавать отдельный .sdc файл. Как я понял, Qsys сама генерит подпбный файл, а как быть с SOPC Builder?
