HYPER_RETIMER Error

Hello Ak_M,

You have probably found a solution... But I ran into the same issue (also DDR3/Arria10). Commenting part of the generated script instance_name\altera_emif_arch_nf_160\synth\instance_name_altera_emif_arch_nf_160_wyghoeq_pin_map.tcl as follows solved the problem:

# with the hyper-retimer, the tdb netlist may contain the full set of routing nodes, so we need

# to search deeper

# if {[expr [get_global_assignment -name "HYPER_RETIMER"] == "ON"]} {

# set var(pll_inclock_search_depth) 250

# set var(pll_outclock_search_depth) 250

# set var(pll_vcoclock_search_depth) 50

# } else {

set var(pll_inclock_search_depth) 30

set var(pll_outclock_search_depth) 20

set var(pll_vcoclock_search_depth) 5

# }

Of course, this is not ideal as this is a file which gets regenerated. However, from Q16.1 this seems to be fixed.
