Well guys...Ive been trying to find a solution for this thing quite few days but could not reach anything till now! Im simply trying to implement a very small system (muliplierbsb--in attachmenet) to send and receive data through the microblaze to my core(Muliplier_VHDL. I created a core(user_logic) in XPS with 3 slave registers. Inside this core I used a multiplier core(Muliplier_VHDL) which I designed. My aim is to write to the slave registers from the microblaze and then read the values in the registers by Muliplier_VHDL core and the write back to a register to be able to read the value written to this register from the microblaze again. After implementing this and trying to download the bit stream I had the following errors ERROR:NgdBuild:455 - logical net 'clk_100_0000MHz' has multiple driver(s): pin PAD on block lmb_bram/lmb_bram/clk_100_0000MHz with type PAD, pin CLKOUT0 on block clock_generator_0/clock_generator_0/Using_PLL0.PLL0_INST/PLL_INST/Using_ PLL_A DV.PLL_ADV_inst with type PLL_ADV ERROR:NgdBuild:924 -

Is it something in the pin assignment? Also concerning the other signals, I totally have no idea whats going wrong. Its my first time to try to integrate a whole system together and communicate with the microblaze, any advice concerning this will be appreciated. Thanks, Eshbon
