Istvan Csomortani 12c95b059d ad_tdd_control: Remove tdd_enable_synced control line
For a better timing and control, the valid control lines are gated with flops, instead of combinatorial logic.
This is the main reason why we do not need the tdd_enable_synced signal anymore. The out coming data is delayed by one clock cycle to keep data and control lines synced.

Istvan Csomortani 593c486168 ad_tdd_control: The state machine goes from OFF to ON, when a valid sync is received 2015-11-24 15:15:53 +02:00
Istvan Csomortani c70be7391f ad_tdd_control: Avoid unnecessary reset on control lines
No need to reset for tdd_last_burst, it's value depends on the tdd_burst_counter.

Istvan Csomortani b17fec689e ad_tdd_control: An active sync pulse can NOT be a reset for the control lines
By reset the control lines (RF, VCO and DP) on an active sync pulse, can cause glitches on the ENABLE/TXNRX lines. The sync pulse resets just the TDD counter.

Istvan Csomortani fc0f4bc414 axi_ad9361: Delete the old sync generator from the core
+ Define two control signal for util_tdd_sync : tdd_sync_en and tdd_terminal_type
+ Delete to old ad_tdd_sync.v instances from the core
+ Update Make files
+ Update ad_tdd_control: add additional CDC logic for tdd_sync (the sync comes from another clock domain)
+ Update the ad_tdd_sync module: it's just a simple pulse generator, the pulse period is defined using a parameter, pulse width is fixed: 128 x clock cycle
+ Update TDD regmap: tdd sync period is no longer software defined

Istvan Csomortani 8ecdb4a4ca library/tdd_control: Add common registers to the register map and fix init value of a register
+ Software in general needs to have access to the VERSION register.
+ tdd_sync_d3 registers init value should be 1'b0

Istvan Csomortani c03983ca54 ad_tdd_sync/control: Update TDD logic
+ Redesign the TDD counter FSM
+ Make the sync logic independent from the tdd control

Istvan Csomortani 5bc16159fa ad_tdd_sync: The resync will reset all the control lines 2015-09-10 11:28:36 +03:00
Istvan Csomortani 85ffc25ec5 ad_tdd_sync: Update the synchronization logic
The synchronization interface is a single bidirectional line. Output for Master, input for Slave.
The sync_period value is relative to frame length and the digital interface clock. The actual synchronization
period will be: sync_period * frame_length * fb_clock_cycle
