Global Set/Reset resources cannot be analyzed in static timing analysis tool for both Nexus and Avant devices. For usage concerns and implementation of the mentioned resource, Users may refer to Global Set/Reset Usage for Nexus Platform App Note ( ...
For differential inputs, users can refer to the example below: COMPONENT SB_IO IS GENERIC( PIN_TYPE : std_logic_vector(5 downto 0) := "000000"; IO_STANDARD: string := "SB_LVDS_INPUT" ); PORT( PACKAGE_PIN : in std_logic; LATCH_INPUT_VALUE : in ...
Generally, Standby Mode refers to the state where both the User logic and the embedded blocks are idle and not performing any function (not toggling). The "Power Controller" block provides an output signal called "STDBY", which the user can use to ...
Solution: When doing VHDL instantiations of SB_RAM modules, the user should provide component declarations. Below is an example for the SB_RAM512x8 module: component SB_RAM512x8 GENERIC ( INIT_0 : bit_vector := ...
