Xilinx App note 138 says only about virtex series, but I coudn't find any documents about readback of virtex2 devices. One more question. Readback methodology of virtex2 is the same with that of virtex/virtex-E? Thank you in advance. -- *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Young-Su Kwon, Ph.

If you open up a bitstream in a binary editor you can read the readback size by looking for the first type II command. 0x30004000 0x500------- rbsize^^^^^^ It is within the first 20 words (32-bit) Steve "Neil Franklin" wrote in message news:6u3csbav6x.fsf@chonsp.franklin.ch... > "Young-Su Kwon" writes: > > > Does anybody know the readback size for virtex2 devices? > > Xilinx App note 138 says only about virtex series, but I coudn't > > find any documents about readback of virtex2 devices. > > > > One more question. > > Readback methodology of virtex2 is the same with that of virtex/virtex-E? > > Both are answered, but in less detail, in: > > http://www.xilinx.com/publications/products/v2pro/handbook/ug012_ch3.pdf > > > -- > Neil Franklin, neil@franklin.ch.remove http://neil.franklin.ch/ > Hacker, Unix Guru, El Eng HTL/BSc, Programmer, Archer, Roleplayer > - Make your code truely free: put it into the public domain
