Description: In PCIe Soft-DMA mode, when an error condition occurs, the DMA IP asserts an interrupt to notify the Host of the detected error. If this interrupt is not properly handled and the DMA is not reset, the system may enter an unrecoverable ...
Version 5.2 of the Lattice PCI Express IP includes an update to use the reset sequence (instead of the 4ms reset timer) requiring the reference clock from the SERDES to be enabled to the fabric. You likely use a .txt file from an earlier version ...
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 ...
Title: PCIe DMA in Ring Buffer Operation Mode Cannot Be Stopped Unexpectedly Issue Description: When the PCIe DMA is configured to operate in Ring Buffer DMA mode for continuous transfers, the DMA operation cannot be stopped unexpectedly. If a device ...
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 under Lattice Radiant, 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 ...
