The error message also says " Unknown range in part select.udp_data_in[((8 * i) + 7):(8 * i)]". But the range is known and depends only on value of i, the loop variable. So I feel it is known. I am confused here. Can someone explain please. " One way to implement this...

Verilog and SystemVerilog (often generically referred to as just "Verilog" in this document) can be written in vastly different styles, which can lead to code conflicts and code review latency. This style guide aims to promote Verilog readability across groups. To quote theGoogle C++ style guide...
Anyway, it does not match with the my requirements regarding space and performance. As part of the investigation, I tested other cores, but I found no much options as good as the TG68 and I even started design a risclized-68000 core, in order to try find a solution. ...
30. Can you tell me about the datatypes in Verilog. Verilog consists of a range of data types essential for design representation. These types serve distinct functions, which are as follows: Wire: Connects hardware components, modeling interconnections between modules. Register (reg): Acts as a ...
