Re: [casper] program ROACH over JTAG
Hello Suraj Thanks for you explanation. Maybe I don't describe clearly. I mean if I want program the FPAG on ROACH over JTAG. Also, the bit file is generated by Xilinx ISE not CASPER toolflow. In this moment, the ucf file of my design is only included the IO pins of my design. But a lot of pins that ROACH are needed are not included in my design. How could I program the FPGA of ROACH with my bit file?

You can do this using the .bit generated by the CASPER toolflow, available in the same location as the .bof. bof files are generated from .bit files using the script 'mkbof' distributed in 'XPS_ROACH_BASE'. A problem I meet is the FPGA pin number assignment. For example, in ISE I select the device is vxs95t and the FPGA pin assignment in ucf file is according to my desing. But ROACH has a lot of FPGA pins which are not in my design but needed for ROACH, sys_clk_n, sys_clk_p, aux0_clk_p, aux_clk_n, ppc_irq_n, ...etc. Part of the magic of the toolflow is that it adds the necessary IO pins to the .ucf depending on which IO blocks you have selected to use (10gbe, adc, etc.). It's part of the reason that IO blocks get special designation as yellowblocks, as they are processed differently for each block. Hence, I can't add these FPGA pins which ROACH is needed into the ucf file of my design. It would definitely be faster to just put the I/O blocks you want to use into a blank model file, and use the CASPER toolflow to generate the .ucf, by un-checking the boxes for 'update system design', 'system generator', and 'ISE/EDK/bitgen' in the 'bee_xps' dialog. This should take about a minute to complete. -Suraj
[casper] Error in PhysDesignRules
Hello I update the error information. While the output of ISERDES (build over Black Box) connects to shared bram of CASPER library, reinterpret, soft register of CASPER library and snap, the error still occurs. Only one situation the error disappears that is the output of ISERDES connects nothing or connects to scope over gateway out. This is very confused me! The simulation in Simulink is OK, but during generateing bof file, the error will occur at mapping stage. And I can get the error message: ERROR:PhysDesignRules:1242 - Invalid connection used for ISERDES. Also the error appears in the input of ISERDES. Any idea? Regards, C-H Cheng
[casper] Error in PhysDesignRules
Hello I use ISERDES to receive data over Black Box. Simulation in Simulink is OK. But while I generate the bof file over bee_xps, the error occurs! The error message is as follows: --- ERROR:PhysDesignRules:1242 - Invalid connection used for ISERDES. The ISERDES comp roach_iserdes_6bit_XSG_core_config/roach_iserdes_6bit_XSG_core_config/roach_i serdes_6bit_x0/iserdes_6bit/Iserdes_master D pin signal roach_iserdes_6bit_gpio_gateway is not driven from an IO. ERROR:Pack:1642 - Errors in physical DRC. --- I also find some information about this error. http://www.xilinx.com/support/answers/31620.htm Should I fix the UCF file? or other idea?
