Soft Error Mitigation Controller – XC7Z015 placer error when using correction by enhanced repair

Description

When implementing the Soft Error Mitigation IP with correction by enhanced repair in 2013.3 Vivado, a placer error may occur:

[Place 30-640] Place Check : This design requires more RAMB18 and RAMB36/FIFO cells than are available in Pblock 'SEM_CONTROLLER'. This design requires 5 of such cell types but only 3 compatible sites are available in Pblock 'SEM_CONTROLLER'. Please consider increasing the span of Pblock 'SEM_CONTROLLER' or removing cells from it.

Solution

As a work-around for this issue, increase the SEM_CONTROLLER pblock size from:

resize_pblock -pblock SEM_CONTROLLER -add RAMB36_X2Y17:RAMB36_X2Y19

to:

resize_pblock -pblock SEM_CONTROLLER -add RAMB36_X2Y17:RAMB36_X2Y21
