10.2.6.2 Axcelerator PLL Parameter Description

The following table describes all the parameters of a subtractor.

Table 10-152. Parameter Description
Parameter	Value	Function
LPMTYPE	LPMPLL	PLL category
LPM_HINT	PRIM	Only primary output
	SEC	Only secondary output
	BOTH	Both outputs
FB	Internal External	Feedback
IFREQ	14.0 - 200.0 MHz	Input Frequency
PFREQ	14.0 - 1000.0	Primary Clock frequency
SFREQ	14.0 - 1000.0	Secondary Clock frequency
DT	STATIC DYNAMIC	Delay type
DELAYSIGN	+ve -ve	Positive or negative delay
DELAYVALUE	0 - 3.75 ns	In steps of 250 psA
CASCADE	Y ES NO	Cascade two PLLs to achieve the required output fre-quency
REFCLKPAD	DEDICATEDEXTERNAL	Source of REFCLK, the Dedicated Pad, or any external net
CLK1OUT	HW RC RN	Clock network to which PLL is connected, Hard-wired Clock, Routed Clock, or Routed Net

Note: In the GUI, the delay is entered directly as a value between -3.75 and +3.75 without breaking it into sign and value.
