+- [AMBA] Writing the testbench for the AHB decoder
+### Comments
+I met some difficulties trying to compile the testbench. After consulting Rishyak, I updated some of my packages and was able to get the executable. The tests weren't successful so I'm trying to debug.

+- [AMBA] Fixing the testbench and the decoder
+### Comments
+I was able to fix through the testbench with the help from Rishyak, got rid of some unnecessary lines of code and replaced them with more concise functions provided by nyu-util such as nyu::reset() and nyu::tick(). I'm currently fixing some bugs with the address calculation in the AHB Simple Decoder module.

+- Readig AMBA specs for designing the AHB-APB bridge
+### Comments
+Turns out that the problem with the decoder testbench was defect on ahb.addr instead of implementation of SimpleDecoder.sv, reported the problem to Rishyak.
+I'm currently reading the APB file and AMBA spec file to design the AHB-APB bridge.
