Avalon Streaming Interface with FIR

I have the following outputs from an FIR

I’ve got a question relating to the FIR compiler 9.1. The picture shows

Source_Valid

Source_SOP

Source_EOP

Source_Channel

Source_Ready is pulled high

Sweep

This is a 2 channel parallel implementation

Sweep2

This is a 2 channel serial implementation

The problem is that EOP should only be 1 clock cycle.

    It is only one clock cycle. Both SOP and EOP must be qualified with VALID. so real_eop = eop & valid.

    Ok, thanks,

    I was just a little concerned that the output signals I was getting didn't look like examples in the FIR compiler manual.
