This article clarifies the clock domain assignments for the MII/GMII interface as described in the Tri-Speed Ethernet IP User Guide (FPGA-IPUG-02084-2.2). The table below includes an amended version of the original documentation to help users ...
Yes, when the received frame length exceeds the max_frame_len register setting, the Receiver of Tri-speed MAC block can still receive the frame correctly. But need to set the flag of rx_stat_vector[31], indicating it’s a long frame, and there is no ...
Description: Following error is encountered when compiling Radiant project with Tri-speed Ethernet MAC IP version 1.4.0, which is due to invalid .ldc file constraint: Error 1026000 Synthesis ERROR - ...
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 ...
