Military ProASIC3/EL DC and Switching Characteristics
Combinatorial Cells ContributionâPC-CELL
PC-CELL = NC-CELL* ï¡1 / 2 * PAC7 * FCLK
NC-CELL is the number of VersaTiles used as combinatorial modules in the design.
ï¡1 is the toggle rate of VersaTile outputsâguidelines are provided in Table 2-22 on
page 2-19.
FCLK is the global clock signal frequency.
Routing Net ContributionâPNET
PNET = (NS-CELL + NC-CELL) * ï¡1 / 2 * PAC8 * FCLK
NS-CELL is the number of VersaTiles used as sequential modules in the design.
NC-CELL is the number of VersaTiles used as combinatorial modules in the design.
ï¡1 is the toggle rate of VersaTile outputsâguidelines are provided in Table 2-22 on
page 2-19.
FCLK is the global clock signal frequency.
I/O Input Buffer ContributionâPINPUTS
PINPUTS = NINPUTS * ï¡2 / 2 * PAC9 * FCLK
NINPUTS is the number of I/O input buffers used in the design.
ï¡2 is the I/O buffer toggle rateâguidelines are provided in Table 2-22 on page 2-19.
FCLK is the global clock signal frequency.
I/O Output Buffer ContributionâPOUTPUTS
POUTPUTS = NOUTPUTS * ï¡2 / 2 * ï¢1 * PAC10 * FCLK
NOUTPUTS is the number of I/O output buffers used in the design.
ï¡2 is the I/O buffer toggle rateâguidelines are provided in Table 2-22 on page 2-19.
ï¢1 is the I/O buffer enable rateâguidelines are provided in Table 2-23 on page 2-19.
FCLK is the global clock signal frequency.
RAM ContributionâPMEMORY
ï¢ ï¢ PMEMORY = PAC11 * NBLOCKS * FREAD-CLOCK * 2 + PAC12 * NBLOCK * FWRITE-CLOCK * 3
NBLOCKS is the number of RAM blocks used in the design.
FREAD-CLOCK is the memory read clock frequency.
ï¢2 is the RAM enable rate for read operations.
FWRITE-CLOCK is the memory write clock frequency.
ï¢3 is the RAM enable rate for write operationsâguidelines are provided in Table 2-23 on
page 2-19.
PLL ContributionâPPLL
PPLL = PDC4 + PAC13 * FCLKOUT
FCLKOUT is the output clock frequency.1
1. If a PLL is used to generate more than one output clock, include each output clock in the formula by adding its corresponding
contribution (PAC13* FCLKOUT product) to the total PLL contribution.
