For XO2, XO3 and ECP3/ECP5 the expected rise/fall time are shown below: Parameter Descriptions Conditions Max (ns) tR Input clock rise time 10% to 90% 1.0 tF Input clock fall time 90% to 10% 1.0
No. Although ispClock products have excellent jitter specifications, the dynamics of their PLLs are very different from those used in data transmission applications (such as those based on ITU-T G.8262). The key difference is in PLL loop bandwidth. ...
Description: The netsanitycheck error indicates general routing is used to drive the IDDR and/or ODDR components. The logic must be modified to use dedicated clock resources: Solution 1: Do not use generic logic (e.g. MUX implemented by LUTs) to ...
Description: Users may encounter an INFO message shown below if there design has an EBR and GSR is disabled. chipcheck: INFO: Design contains pre-loadable EBR during configuration that has a requirement: Since the GSR is disabled for the EBR, make ...
Lattice does not have any data regarding the gate counts for a device. Only the Look-Up Table (LUT) counts are available for a device. The reason is that an LUT can be configured in an end design either as INVERTER or 4 input AND gate. The actual ...
