Requirements with which the SLIDAS MUST comply

    Push buttons

    1. RUN/STEP. The behaviour of the SLIDAS depends on the position of the DUTY TYPE rotary switch:
    2. INJECT ERROR. As the name indicates, this button is used to simulate the presence of errors in a S-LINK. Pressing the button will set a flag in the SLIDAS. When the SLIDAS next transfers a data block, it will take the flag into account and generate the error detection signals in a way that depends on three switches:

    Switches

    1. LDOWN. Setting this switch to ENABLE will cause the SLIDAS to simulate that it detected a problem rendering the virtual S-LINK not functional. The signal LDOWN# is then set low. When setting the switch back to DISABLE LDOWN# will remain at its low level until the ROMB starts a reset cycle with URESET#.
    2. DATA ERROR. Setting this switch to ON causes the SLIDAS to simulate the presence of an error on the fourth word of the block that contains the error(s). See the push button INJECT ERROR.
    3. CTRL ERROR. Setting this switch to ON causes the SLIDAS to simulate the presence of an error on the ending control word of the block that contains the error(s). See the push button INJECT ERROR.
    4. FEMB/LDC. The SLIDAS is designed to work as a dummy LDC. However, due to the similarity between the protocols of the S-LINK connectors at both the source and the destination ends, the SLIDAS can easily act as a FEMB. The difference between the protocols is merely that the signal arriving to UXOFF# at the LDC is asynchronous whereas the equivalent signal LFF# at the FEMB is synchronous.
    5. BLOCK/WORD.
