Derived parameters are: lm=3.29995e-09, ctot=3.65e-13. -* -* It is important to note that the model is a simplified one - the -* following assumptions are made: 1. The self-inductance l, the -* self-capacitance ctot (note: not c), the series resistance r and the -* parallel capacitance g are the same for all lines, and 2. Each line -* is coupled only to the two lines adjacent to it, with the same -* coupling parameters cm and lm. The first assumption implies that edge -* effects have to be neglected. The utility of these assumptions is -* that they make the sL+R and sC+G matrices symmetric, tridiagonal and -* Toeplitz, with useful consequences (see "Efficient Transient -* Simulation of Lossy Interconnect", by J.S. Roychowdhury and -* D.O Pederson, Proc. DAC 91). - -* It may be noted that a symmetric two-conductor line is -* represented accurately by this model. - -* Subckt node convention: -* -* |--------------------------| -* 1-----| |-----n+1 -* 2-----| |-----n+2 -* : | n-wire multiconductor | : -* : | line | : -* n-1-----|(node 0=common gnd plane) |-----2n-1 -* n-----| |-----2n -* |--------------------------| - - -* Lossy line models -.model mod1_test ltra rel=1.2 nocontrol r=0.2 l=5.83005279316e-09 g=0 c=4.55000000187e-13 len=24 -.model mod2_test ltra rel=1.2 nocontrol r=0.2 l=1.24299471863e-08 g=0 c=2.75000000373e-13 len=24 - -* subcircuit m_test - modal transformation network for test -.subckt m_test 1 2 3 4 -v1 5 0 0v -v2 6 0 0v -f1 0 3 v1 0.707106779721 -f2 0 3 v2 -0.707106782652 -f3 0 4 v1 0.707106781919 -f4 0 4 v2 0.707106780454 -e1 7 5 3 0 0.707106780454 -e2 1 7 4 0 0.707106782652 -e3 8 6 3 0 -0.707106781919 -e4 2 8 4 0 0.707106779721 -.ends m_test - -* Subckt test -.subckt test 1 2 3 4 -x1 1 2 5 6 m_test -o1 5 0 7 0 mod1_test -o2 6 0 8 0 mod2_test -x2 3 4 7 8 m_test -.ends test -* -x1 648 748 651 751 test -* -* -vdd 1 0 DC 5.0 -VK 267 0 DC 5.0 -* -VS1 168 0 PULSE (0 5 15.9N 0.2N 0.2N 15.8N 60N) -VS2 268 0 PULSE (0 5 15.9N 0.2N 0.2N 15.8N 60N) -* -.control -TRAN 0.2N 47.9NS -PLOT v(648) v(651) v(751) -.endc -* -.model mn0p9 nmos LEVEL=1 vto=0.8V kp=48u gamma=0.3 phi=0.55 lambda=0.0 -+ PHI=0.55 LAMBDA=0.00 CGSO=0 CGDO=0 CGBO=0 -+ CJ=0 CJSW=0 TOX=18000N NSUB=1E16 LD=0.0U - -.model mp1p0 pmos LEVEL=1 vto=-0.8V kp=21u gamma=0.45 phi=0.61 lambda=0.0 -+ PHI=0.61 LAMBDA=0.00 CGSO=0 CGDO=0 CGBO=0 -+ CJ=0 CJSW=0 TOX=18000N NSUB=3E16 LD=0.0U - -.END |
