truesim - Simulate the flattened network

Simulates a network with a set of input vectors. Before calling this command, the user should create a partition (using the command build_partition_mdds). The simulation vectors can be provided by the user (using -f vectors_file), or generated randomly.

Command options:

-D <filename>

File to dump randomly generated vectors. Primary input probability file SHOULD be specified with -p option.

-d

Perform event-driven true delay simulation. The fanout count of the nodes is used as an estimate for the node delay. Primary inputs are assumed to have arrival times of zero.

-f <filename>

File containing simulation vectors. The format is simple but strict and hence, few checks are made. The file format is as below:

.i c n d o e p f q g r h s i t j u k a l b m
.s
0 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 0 1 1 1 1 ;
0 1 1 0 0 0 0 1 0 1 1 0 1 1 1 1 0 0 0 0 1 ;
0 0 1 0 0 0 0 1 0 1 0 0 0 1 0 1 0 0 0 0 1 ;
0 1 1 0 0 0 0 1 1 1 1 1 1 1 1 1 0 1 0 0 1 ;

The .i statement specifies the primary inputs of the network. The patterns start after .s key word. Each vector is a space separated list of bits and ends in a semi-colon. The length of any vector should be equal to the number of signals specified in the .i statement. A line starting with # is a comment.

-g <filename>

File to output random probabilities for primary inputs. Use this option ONLY to produce a vector of signal probabilities for primary inputs. This option does not proceed with simulation.

-h

Print a help message that details all options.

-n <N>

Number of patterns to simulate. The default is 1000. Use this option ONLY with -p option.

-p <filename>

File containing primary input probabilities. The format is as shown below:

PI_Name1 0.67
PI_Name2 0.45

-r <N>

Print PI/PO names after every N patterns simulated, for better readability of simulation output. This option is effective only when the verbosity flag is on.

-T <filename>

File containing node delay and load values. The file format is as shown below:

node1 delay1 load1
node2 delay2 load2

The delay vaues are assumed as specified in a common unit. The same is true for load values too.

-t <time>

Time in seconds allowed to finish the simulation. The default is no limit.

-v <N>

Specify verbosity level, N.
