Description: The issue may be due to misaligned data. It should be noted that EPCS-bypassed mode does not have any word alignment capability. However, there is a workaround by using epcs_skipbit_i input signal to correct the data alignment at the ...
There is a PMA register responsible for data polarity inversion that could be written through the APB interface on 10G PCS IP. From Table A.26 of FPGA-TN-02245, look for rx_polinv and tx_polinv where in writing 1 on this register bit will trigger the ...
The Clock Tolerance Compensation (CTC) logic in the SGMII and Gb Ethernet PCS IP Core performs both idle ordered set insertion when the CTC FIFO low watemark is reached and idle ordered set deletion when the CTC FIFO high watemark is reached. CTC ...
Lattice currently recommends the following for implementing Gigabit Ethernet interfaces: CertusPro-NX FPGAs: Use SERDES-based SGMII or RGMII Certus-NX, MachXO5-NX, and CrossLink-NX: Use RGMII These recommendations are based on updated LVDS-based ...
Lattice Technical Support Expectation Please be advised that highest priority for Lattice Technical Support will be given to 1. Software which is not working as expected or suspected bugs. We recommend that customers use the latest software tools and ...
Glitch Fliter is used to prevent short-duration events of glitches, This is used to prevent False tripping on noise in a system. GLITCHFilter in device constraints , enables 1ns glitch filtering.
Description: In simulating designs for Lattice devices, this error may appear if there is no GSR instantiated in the testbench. Solution: There is no planned fix for this simulation issue. To work around this, please instantiate GSR on your ...
Solution: The following RDs available for Crosslink-NX will support the said applications: 1. FPGA-RD-02212 : N Input to 1 Output MIPI CSI-2 Side-by-Side Aggregation - Aggregate multiple Image Sensors into a single Output with Minimal Latency. - Uses ...
