Generic

ResetGen

Generating a reset pulse with initial 0 state.

TriStateBuffer

Instantiation of n-bits tri-state buffers. Each lines could have common (TriStateBuffer) or different (TristateBufferAtomic) directions.

MachXO3

ReverseClock

A PLL instanciation of MachXO3 to reverse clock (180° phase).

ECP5

Gowin

Some primitives blackboxed instanciation :

• OSC : internal oscillator blackbox
• Gowin_OSC : internal oscillator with FREQ_DIV parameter
• PLLVR : Some PLL instanciation for TMDS and HyperRam
• RPLL : PLL instanciation mainly for GW1NR-9
• CLKDIV: clock divider (by 5 default)
• TMDS_PLLVR: PLL block generated by gowin ide to drive TMDS blocks
• OSER10: 10:1 serializer with friendler module named Oser10Module
