This module creates sync header alignment described in section 7.6.1 of
the JESD 204C specification.
The alignment relies on the bitslip capability of the connected
transceiver.
Create a common 'run_tb.sh' script to be called by every testbench.
Unify file and testbenches names.
Fix util_pack/cpack_tb.
Add parameters '-batch' and '-gui' for modelsim and xsim simulators (default is gui)
Add ascript for that generates output in xml format (used by CI tools).
get_cell on i_lmfc/cdc_sync_stage1_reg doesn't return anything because design was updated.
This generates a CRITICAL WARNING and since the constraint it not necessary anymore, it can be deleted.
If Tx source synchronous clock is not routed through clock capable pins
the interface and driving logic must run on the Rx interface clock.
This introduces a dependency, Rx interface must be bring up before the
Tx. In this mode a Tx only operation is not possible.
This is done through a synthesis parameter.
Expose this parameter to the software so it can query if the limitations
exists in the implementation.
If the REMOVE_NULL_BEAT_EN is set, in FIFO mode, all the beats with a
NULL TKEEP will be removed from the AXI stream.
This feature is used initially in data_offload, to create a continues and
cyclic TX data stream for DACs, when the IPs in the path have different data
widths.
Dual clock mode is introduced in link layer to support different
datapath widths on the transport layer than on physical layer.
- Link clock : lane rate / 40 for input datapath width of 4 octets 8b10b
- Device clock : Link clock * input data path width / output datapath width
Supports four clock configurations, single or dual clock mode with or
without external device clock.
The configuration interface reflects the dual clock domain.
Support multiple clock monitors in a block.
Before this change the clock monitor had to be named with a fix name
preventing multiple instances of the clock monitor.
Add parameter that describes interface to link layer, this must be
integer multiple of octets per frame.
Add parameter that describes interface to user/DMA, this must be
multiple of bytes so software can process the samples easier.
