Looking at a Spartan 3E FPGA, which costs around $10, and the smallest Virtex 4 which costs around $150, why is there such a big difference in price between these two families? Also, when will the new Kintex and Artix chips be out? They claim Virtex 6 performance at less than half the cost. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
