2. Peter JansweijerATLAS week: February 24, 2004Slide 2 MROD-In design from Altera to Xilinx Altera APEX20K200EQC240-1 Total logic elements –5605 / 8320 (67 %) Total ESB bits –15360 / 106496 (14 %) Total pins –168 / 171 (98 %) Xilinx XC2VP7FG456-7 Number of SLICEs –2898 out of 4928 (58%) Number of RAMB16s –3 out of 44 (6%) Number of External IOBs –168 out of 248 (67%) Note 1: Rule of thumb 70 % = FULL. If you try to put more in your FPGA then you’ll probably face routing and timing problems! Note 2: 1 Xilinx “SLICE” (~ 2 “Logic Cells”) ~ 2 Altera “Logic Elements”

13. Peter JansweijerATLAS week: February 24, 2004Slide 13 Conclusions: Design can easily be ported from Altera to Xilinx RocketIO –GOL Receiver is working. –Inter FPGA link to be tested. Power PC –Consumes FPGA resources (probably need a XC2VP20 instead of a XC2VP7 device) –Needs investment in learning EDK –Needs investment in software development

Note 1: Rule of thumb 70 % = FULL. If you try to put more in your FPGA then you’ll probably face routing and timing problems! Note 2: 1 Xilinx “SLICE” (~ 2 “Logic Cells”) ~ 2 Altera “Logic Elements”

16. Peter JansweijerATLAS week: February 24, 2004Slide 16 First Rough Worst Case Timing Estimate XC2VP7FG456-5 Fail 2 Constraint (-35 ps) XC2VP7FG456-6 Fail 1 Constraint (-11 ps) XC2VP7FG456-7 Okay (40 ps) XC2VP7FF896-5 Fail 1 Constraint (-884 ps) XC2VP7FF896-6 Okay (23 ps) XC2VP7FF896-7 Okay (25 ps) Xilinx fitter tries to exploit the full timing budget that is set in the constaints file. Therefore conclusions are hard to make… Failed constraints are on “Clkx2” (80 MHz)
