Hi I’m writing an assertion to check the time difference between a clock signal and a reset. The requirement is that the delay between refclk and resetb should be greater than 90 us. This is the assertion that I have written property clk_before_resetb(time delay); rea...
Once in a while we receive questions from customers regarding the difference between RTL (behavioral) simulation and gate-level simulation. Many times the issue is traced to a flipflop in the design. For a flipflop with both asynchronous set and asynchronous reset, the...

Difference between logic [7:0][3:0] ARRAY; and logic ARRAY [7:0][3:0]; in system verilog March 3, 2008, 8:36pm2 When you declare an array, there are two types of dimensions: packed and unpacked. For example, imagine you have a variable that is 12 bits wide: ...
The SD SmartDifferencer shows the differences between two versions of source code in terms of abstract editing operations applied to programming language constructs. The language constructs are discovered by parsing the code using a production language parser (and depending on language, determining scopes...
PURPOSE: An apparatus for calculating the absolute difference between binary integers is provided to obtain the absolute difference of binary signed or unsigned values in one instruction cycle, and keep arithmetic precision in calculating the same by detecting an overflow. CONSTITUTION: An inverter circu...
