Hi, I am new to openroad flow. i successfully studied the examples given in the tutorial and was able to run the flow for given examples and a small test design. but while i run the flow for a larger design that uses a 128x512 bit memory it is showing an error "ERROR: Syntheized memory size exceeds maximum allowed bits 4096". is anyone aware of this error?

Without test case difficult someone to help you. Check this configuration on how to use pre-hardened sram directly with your design. https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts/blob/master/flow/designs/sky130hd/coyote_tc/config.mk

Thank you for your reply. I will go through the configuration.

You really want a ram macro for such a large RAM. Synthesizing it out of flops will be quite inefficient. If you really want to proceed you could disable the check

Thank you so much for your reply. I will try to use the ram macro.
