• Lattice Radiant: Why is the bitstream file size fixed (ex. Always 1.8Mb) even in small designs for Certus-Pro NX?

  Certus Pro-NX, the BIT file size on simplest design is 1.8MB, while for Crosslink-NX it generates 790KB. Whenever design becomes more condensed (especially more usage of EBRs and LRAMs) bitstream size will increase from that 1.8MB. The bitstream size ...

  The bitstream file size increases even with a small modification. The bitstream comprises both fuse data frames (SRAM configuration bits) and EBR initialization information. Fuse data frame size is fixed for the given device irrespective of how huge ...

  Yes, there is a difference in size between encrypted and unencrypted bitstreams. An encrypted bitstream has additional overhead associated with the bitstream. Therefore an encrypted bitstream's size is slightly larger than an unencrypted bitstream. ...
