A.4. Channel Logical Register Map
Stratix 10 Channel Register Map Summary
Feature | Feature Description |
---|---|
Pre-emphasis | Boost high frequency component by de-emphasizing low frequency components to compensate the low-pass characteristics of the physical medium. |
VOD | TX output differential swing. |
TX Compensation | When enabled, it reduces the PDN induced ISI jitter. |
Slew Rate | This attribute of the TX PMA is datarate dependent and is important when doing datarate reconfiguration. |
Loopback | The PMA supports serial, pre-CDR reverse serial and post-CDR reverse serial loopback paths. |
RX PMA | This attribute of the RX PMA is datarate dependent and is important when doing datarate reconfiguration. |
Setting RX PMA Adaptation Modes | RX PMA adaptation supports the following modes:
|
Manual CTLE | You can use the CTLE in Manual Mode. This section describes how to set the values. |
Manual VGA | You can use the VGA in Manual Mode. This section describes how to set the values. |
Adaptation Control - Start | In the adaptive modes, this section describes how you can start adaptation. |
Adaptation Control - Stop | In the adaptive modes, this section describes how you can stop adaptation. |
Adapted Value Readout | In the adaptive modes, this section describes how you can read the adapted values. An example is this sequence for reading adapted VGA value: STEP 1: Set pm_cr2_tx_rx_testmux_select to 4'b1011 STEP 2: Set adp_status_sel to 6'b000101 STEP 3: Read testmux[4:0] as the adapted VGA value. |
CDR/CMU and PMA Calibration | Enables user to optimize CDR/CMU and PMA performance when changing the data rate and reference clock. |
Reset | Enables the reset of the channel TX, RX PCS, and PMA. |
Optional Reconfiguration Logic PHY- Capability | Enables Native PHY channels' capabilities to be readable. |
Optional Reconfiguration Logic PHY- Control & Status | Enables users to read the status of channel and control the channels' behavior. |
Embedded Streamer (Native PHY) | Enables logic in Native PHY to store the individual profile information and perform .mif streaming. |
Square Wave Generator | Square wave generator can be used to provide a simple way to simulate traffic. |
PRBS Generator | PRBS generator can be used to provide a simple way to simulate traffic. |
PRBS Verifier | PRBS Verifier can be used to provide a simple and easy way to verify and characterize high-speed links. Note that you must also configure the registers under "Other registers needed for PRBS verifier" in order to use this feature. |
EMIB-related registers needed for PRBS Verifier | Used only in conjunction with the PRBS Verifier feature. |
Static Polarity Inversion | Static polarity inversion can be used to easily invert the polarity of the TX or RX serial data or both. |
PRBS Soft Accumulators | PRBS soft accumulators can be used to count the number of accumulated bits and errors when the hard PRBS blocks are used. |
