Verilog defparam mydll.mypll_0_0.LOCK_DELAY=500; mydll dll_inst(.CLKI(clkin), .CLKOP(clk1), .CLKOS(clk2), VHDL Not supported For back annotation simulation LOCK_DELAY needs to be set in the preference file. Below is an example for the PLL. ASIC "pll/pll_0_0" TYPE "EHXPLLA"...
https://github.com/verilog-to-routing/vtr-verilog-to-routing/blob/master/ODIN_II/SRC/odin_ii.cpp#L333:L337 . Also he already made a conversion script to get these back. The principle is that Odin puts the clock information within the latch name and the conversion simply takes these and ...
Kind Code: A1 Abstract: In a first clock frequency multiplier, multiple injection-locked oscillators (ILOs) having spectrally-staggered lock ranges are operated in parallel to effect a collective input frequency range substantially wider than that of a solitary ILO. After each input frequency change...
One skilled in the art of digital design can convert the pseudo code of Table 4 to a hardware definition language such as Verilog to implement the circuit.TABLE 4 DELTA = P − (FT_INC * M) SIGMA = DELTA + LATCH IF RESET then LATCH=(M−1)...
We can describe a multiplier that takes multiple clock cycles to compute its result using a shift-and-add method. The following process, based on an example in the IEEE 1076.6 standard, describes the behavior: MultProc : process is begin wait until rising_edge(clk); if start = ‘1’ then...
the multiplier is designed for a fixed-point operation, the Idea of the multiplier is that the ordinary multiplier is worked for two positive fixed-point number, so it is needed to ensure that the two multiplicands are positive to give the correct answer, so if one of the inputs or bot...
Below is a snippet of the generated model with the estimated critical path highlighted. The estimated critical path is now only through a single multiplier block because distributed pipelining broke up the long chain of adders in the Discrete FIR Filter by inserting pipelines throughout the original...
11. The processor as recited in claim 10 wherein the first subcircuit comprises an adder circuit and wherein the second subcircuit comprises a multiplier circuit. 12. The processor as recited in claim 11 further comprising a third subcircuit clocked by at least a third clock of the plurality...
TABLE 5 provides pseudo code, which can be converted into a hardware definition language such as Verilog, for the embodiment of phase controller630used in example of FIGS.7(a)-7(d). TABLE 5 STANDBY MODE: DV = DV_MAX * P_S.
