Adrian Costina c32b4b02f3 sync_bits: Change I/O names of wires "in" and "out" for VHDL users 2019-04-23 18:03:23 +03:00
Lars-Peter Clausen d72fac4b1e Add missing timescale annotations
For consistent simulation behavior it is recommended to annotate all source
files with a timescale. Add it to those where it is currently missing.

Istvan Csomortani d18eb85e41 jesd204:tx_ctrl: Update the sync_request logic
The cfg_links_disable register will mask the SYNC lines, disabled links
will always have a de-asserted SYNC (logic state HIGH).
The FSM will stay in CGS as long as there is one active link with an
asserted SYNC (logic state LOW).

Update the test bench to generate the SYNC signals in different clock
edges, so it can test all the possible scenarios.

Istvan Csomortani da03572b32 jesd204_tx: Add dynamic multi-link support
A multi-link is a link where multiple converter devices are connected to a
single logic device (FPGA). All links involved in a multi-link are synchronous
and established at the same time. For a TX link this means that the FPGA receives
multiple SYNC signals, one for each link. The state machine of the TX link
peripheral must combine those SYNC signals into a single SYNC signal that is
asserted when either of the external SYNC signals is asserted.

Dynamic multi-link support must allow to select to which converter devices on
the multi-link the SYNC signal is propagated too. This is useful when depending
on the use case profile some converter devices are supposed to be disabled.

Add the cfg_links_disable[0x081] register for multi-link control and
propagate its value to the TX FSM.

Istvan Csomortani 09ff1f3a77 jesd204: Fix file names
All the file names must have the same name as its module. Change all the
files, which did not respect this rule.
Update all the make files and Tcl scripts.
