[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
Re: [casper] I2C driver
Hi Mellisa. Have you already developed an I2C driver for the ROACH board? I've added the iic master controller I wrote for our katadc to the casper svn at: http://casper.berkeley.edu/svn/trunk/mlib_devel_10_1/xps_lib/pcores/kat_iic_controller_v1_00_a/ It is a very simple interface, designed to handle high latency (tcpborphserver). There is some documentation at: http://casper.berkeley.edu/svn/trunk/mlib_devel_10_1/xps_lib/pcores/kat_iic_controller_v1_00_a/doc/ Currently it is in no way integrated into the toolflow.
