    • An IC that includes an eye viewer and a BER checker coupled to the eye viewer, where the BER checker receives a serial data signal from the eye viewer, is provided. In one implementation, the BER checker receives the serial data signal from the eye viewer without the serial data signal passing through a deserializer. In one implementation, the BER checker compares the serial data signal against a reference data signal to determine the BER for the serial data signal. In one implementation, the IC includes an IC core coupled to the eye viewer and the BER checker, where the BER checker is outside the IC core. In one implementation, the BER checker is a dedicated BER checker. In one implementation, the BER checker includes an exclusive OR gate, a programmable delay circuit coupled to the exclusive OR gate, and an error counter coupled to the exclusive OR gate.
    • 提供了一种IC,其包括耦合到眼睛观察者的眼睛观察器和BER检查器,其中BER检查器从眼睛观察器接收串行数据信号。 在一个实现中,BER检查器从眼睛观察器接收串行数据信号,而不经过串行数据信号通过解串器。 在一个实现中,BER检验器将串行数据信号与参考数据信号进行比较,以确定串行数据信号的BER。 在一个实现中,IC包括耦合到眼睛观察器和BER检查器的IC核心,其中BER检验器在IC核心之外。 在一个实现中,BER检查器是专用的BER检查器。 在一个实现中,BER检查器包括异或门,耦合到异或门的可编程延迟电路和耦合到异或门的错误计数器。
