Power consumption of an LSI chip is estimated at the beginning stage of the designing without using the HDL description. An I/O part power of a new designing LSI chip is calculated by an equation with using the outside specifications required by the application of the LSI chip. An I/O part power of an original LSI chip is calculated by the outside specifications, the core circuitry part power of the original LSI chip is calculated by subtracting this calculated I/O part power of the original LSI chip from the known total power of the original LSI chip, and converting the voltage and process and frequency, the core circuitry part power of the new designing LSI chip is calculated. The kinds of functions, voltage, frequency, the number of gates, unit capacity and clock structure of the new designing LSI chip are given and referring to the data base of ratio of each function described the ratio of the number of FF and the ratio of clock power/logic power, the clock system power is calculated by the number of FF and the clock structure. The logic system power is calculated by the ratio of the clock power/the logic power. The modifiable circuitry part power is calculated by summing up the I/O part power, the core circuitry part power, the clock system power and the logic system power.

Estimation system of LSI power consumption

A hierarchical layout designing method for an LSI has the step of determining the layout positions and shapes of hard macro blocks and a soft macro block, the step of forming a wiring which connects the hard macro blocks to each other and a path which passes above the soft macro block, the step of evaluating the influence which a wiring passing above the soft macro block will influence on the internal wiring of the soft macro block, a determination step of determining the extending direction in which the cell rows are to extend in the soft macro block, the step of forming in the soft macro block the cell rows in which cells are to be placed, and the step of calculating a first cost 'COST x' in the case where the cell rows are formed extending in an x-axial direction and a second cost 'COST y' in the case where the cell rows are formed extending in any-axial direction. By the determination step, the first cost 'COST x' and the second cost 'COST y' are compared with each other, and a direction in which the lower one of the first and second costs is attained is determined as the extending direction of the cell rows.

Layout designing method and layout designing apparatus

In the chip layout of an LSI, a layout near bonding pads is efficiently optimized. Especially in a chip having a large number of pins, an increase in chip size caused by pad necks can be prevented. Normal functional macro-blocks are arranged in an inner region of the LSI. On the other hand, input/output blocks including corner blocks are arranged at the peripheral portion of the LSI. In addition, pads separated from the input/output blocks are arranged on the LSI including portions near the corner blocks, and the input/output blocks and the pads are connected to each other through wiring lines.
