In order to help timing closure on multi SLR FPGAs add a pipeline stage
between the link layer and physical layer. This will add a fixed amount
of delay to the overall latency.
Bus sizes often depend on parameters. In such cases the physical indexes
of the interfaces from the multi bus must be calculated based on parameters.
For each interface expose the formula that calculates the indexes to the
block design.

When using a non-maximum sampling rate the data is captured earlier by two
samples.
After the initial trigger jitter fix, a low latency/utilization was
desired(one sample delay for the trigger detection). After adding the
instrument trigger an equal latency between ADC and LA was required, hence the
need for a two sample delay on the trigger path. The delay was implemented
as two clock cycle delays not two sample delays.
This commit fixes this issue and offers a more robust design.
A trigger jitter was added by fix on the external trigger input. It
manifests at input sampling frequencies lower than the maximum frequency.
Added the required reset and CE(valid) signal to the last output
stages of the trigger to obtain the desired functionality for all
sampling rates.
The extra delay was added on the trigger and data paths to compensate
for the logic analyzer changes.
The extra delay will be also seen on the m2k daisy chain. The
delay between devices will be increased from 3 to 4 samples delay.
Fix external trigger for low sampling rates.
Because the external trigger can be a short pulse at high decimation rates
there is a high chance that the pulse will be missed.
xsim does not like if a register or wire is used before their
definition. Make sure the every register and wire is defined before it's
used the first time.
