Web15 lug 2013 · It is not clear that you want to perform the CRC over 9bits or have 9 bits of data and want to use an 8-bit CRC. You need to understand hamming distance and error detection capabilities. A CRC by itself is no enough; you need to understand the protection it provides. This answer is given in the spirit of what Verilog CRC would look like. Web14 ott 2015 · A one-hot state machine is generally faster than a state machine with encoded states because of the lack of state decoding logic. SystemVerilog and Verilog has a unique (pun intended) and efficient coding style for coding one-hot state machines. This coding style uses what is called a reverse case statement to test if a case item is true by ...

SystemVerilog introduces a new 2-state data type—where only logic 0 and logic 1 are allowed, not X or Z—for testbench modeling. To distinguish the old Verilog 4-state behaviour, a new SystemVerilog logicdata type is added to describe a generic 4-state data type.
